Here's an issue I just noticed late last night. My CPU seems to be stuck at max. I've tried different governors, wiped cache/dalvik and reflashed kernel and rom. I also killed all running apps to see if an app was causing it, to no avail.
Here's what really stumps me, my battery life seems fantastic. Not what I'd expect if my CPU is running at 100%. Could there be an issue with detecting CPU speed? As I mentioned before, trying different governors doesn't help with scaling but I notice when I select "powersave" my CPU jumps from max to the minimum value and stays there, still not scaling.
Before someone mentions I did search before posting. Went through the threads, tried the suggestions within and still have the problem. Hence why I'm posting here now.
Am I overlooking something? Any help will be appreciated, thanks!
Edit: My current rom and kernel are in my sig.
so are you monitoring this via setcpu on Decks?

Yes I am, is there a known issue?
My understanding is that having both setcpu and the native CPU performance running will result in some conflict. that is probably the problem, but I don't know how to monitor the scaling with the native performance. so i see what you are trying to do.
I never run setcpu on CM7 or Decks because it is built in, but if the battery life is alright, it would appear the built in takes precedence.
Is there a good way to monitor the CPU without setCPU? Thanks

check out "system panel"
edit: or android system info app > system tab > cpu. gives you a break down of time (%) spent at each frequency.
Thanks, I like that app a lot.
Unfortunately even after deleting setCPU I'm still seeing 100% CPU usage. According to system panel the System is using 80%.
Edit: I am underclocked to 499MHz, and that's where she's pegged. Still oddly enough I'm getting the best battery life I've seen in weeks.
My CPU doesn't scale correctly either. Its either running at MAX, Deep Sleep, or 245mhz. Never does it use the in between frequencies no matter what govenor I use(I have tried them all). I use CPU Spy to check scaling and No Frills CPU to change the governor both are from the market.

so if you do this:
or android system info app > system tab > cpu. gives you a break down of time (%) spent at each frequency
what is the frequency while it is sleeping?
1. you may need to overclock just a bit
2. you may want to reflash rom without wiping the data and see if that helps
3. every phone is slightly different, so yours may need more time to process the commands at 499, especially if you are undervolted as well. which is why you getting pegged.

Thanks, says the time spent at 499 MHz is 92.51%. I don't think underclocking is the issue. If I overclock to 1113MHz it will peg there as well. Seems to only go 100% when screen is on however according to the system panel app. I'll try your suggestion in (#2) and report back.
Tried reflashing the rom without wiping. Still have the same issue. So odd. I'll try a different kernel just to see if that helps, but I'd hate to part with my 3.3.7 LEE kernel.
Last thing I can think of is doing a full wipe, but I'd like to avoid that if I can.
Definitely experiencing the problem with other kernels. I'm out of ideas.
Did you try tiamat 4.1.0? I'm using it now and the battery life is right there with 3.3.7.

Did you restore any apps with titanium backup by chance?
Sent from my PC36100 using XDA App
By the way, I appreciate all your help alaman68.
Tiamat 4.1.0 was the other kernel I tried. No luck. Also I've never used titanium backup to restore apps. I'm stumped as to why my CPU won't scale anymore. The Android System seems to be using as much as I allow it.
Trying, you could try a sense rom for a day and check the scaling for a benchmark.
Is there anything else you are running? Undervolting, v6... Anything else?
Not undervolting as my phone never liked it. Nor running V6 or any other scripts either. I'll try flashing a sense rom, see if I have the same problem there. Or else, think doing a full wipe and reflash everything would help?
if all else fails, a clean flash won't hurt. Even get a new download. Gotta ask, did everything properly? you using amon_ra recovery? did you download any new apps when that started happening?
I may just have to. I suppose there's always a chance I made a mistake somewhere, but I've been at this rooting/flashing thing for a long while. Thing is, everything was fine up until I noticed it last night.
I'll do a clean install. I can always nand restore if it doesn't work. (Save me the time to set up everything.)
I'll report back
Did a clean install and guess what, my CPU is scaling again! There must have been a conflict somewhere. Thanks again alaman68 for all your help and suggestions. Sometimes these phones get gremlins I tell ya.

so im currently running MCK 2.2 rom with the updated kernel but without compcache enabled because i havent been able to get it working yet.
here's the problem though, about once a day my phone will slow down to an unberable speed... just like it used to with the OEM Rom.
when I open up SetCpu (which i know isnt supposed to do anything on the hero) it tells me that my CPU is running at 245mhz, but the control bars in SetCPU are set for 528/480mhz... when i hit refresh the phone comes back up to 528/480 and its fast(er) again...
anybody have any ideas on this one?

I have a similar problem. I experience serious slowdowns (compcache enabled or disabled) about once per day. I have not verified the CPU speed as I'm not using SetCPU. I am using the "performance" governor in MCK.
My typical solution is a reboot.
im just curious if this is the original problem or a new one cause by this rom setup... because I dont ever recall reading anything about the CPU getting stuck at 245mhz from sleep mode being the source the slow downs....
Have you tried disabling the location services to verify it's not that particular bug you're seeing/experiencing?

I look in the kernel and there are two sets of settings: The profiles and a set of setting for the kernel speed (this is split into min/max for screen on and min/max for screen off)
For screen on, it is set for 480000 min/528000 max
For screen off, it is set for 245760 min/245760 max
If the screen is off, it's possible that the kernel went into the lower settings and didn't come back.
I've heard different reports on whether the profiles work in the Hero. I'm curious myself. I do know the stock rom has everything locked, but since the kernel source has been released and Modaco released his kernel, I'm not so sure if the lock statement is true anymore.
I'm compiling a kernel as we speak with the cpu frequency scaling on. Had some issues with the cpufreq.h file not seeing two variables necessary for the userspace profile, but hopefully I was able to fix that (won't know until I run it).

Ok, modaco rom sets the governor to "performance" on boot. This essentially "sticks" your CPU to max throttle.
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
Will tell you where you are, governor wise..
I'm not entirely sure what setCPU does, I've never used it, but I assume it just tweaks your top and bottom Mhz and maybe changes governor to performance when the screen is on? If it's configured properly? Maybe not, who knows?
If you want the best battery life, put the governor back to msm7k, it's a custom governor modified by HTC to make your battery last longer.
I changed the following line in modaco.sh:
echo "performance" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
to:
echo "msm7k" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_govern
and haven't noticed any slowdown from it.. my battery is lasting longer than it did on Stock or Fresh 1.1...
i had SetCPU installed on my phone, and when the phone would shut the screen off, by timing out or being locked, it wouldnt wake up from sleep.. i know at least one other person this has happened to, but removing SetCPU got rid of that problem.. does anyone know whats up?
You're lucky. SetCPU didnt even work on my SGS. It just FC'd everytime I loaded it. I didnt have root, which probably accounts for this issue, however it should still load up - just with locked speed setting bars.
I had the exact same problem you have mentioned below. I also get this issue with the autokiller app.

I'm pretty sure that SetCPU won't work with the SGS as things stand, root or not, for changing the clock rate (unless that built-in thingamagig for unlocking HTC phones' clock rates works).
Did you make sure no default profiles were set up when you installed SetCPU that were set to underclock the CPU or do anything else weird when the phone goes to sleep/is idle? That would be a good place to start.
If anyone could get me a log (force close/crash) or a /proc/last_kmsg (reset) that would be great.

I'm sure someone's probably told me before, but how would we do this?
I installed SetCPU, I have root, but it just FC all the time
When rooted setup works fine as long as you just use it for monitoring and don't change the profile

Okay, that's odd. It's worked this time, although I did nothing different.
coolbho3000, tell me what I need to do to send a logcat and I'll use profile to see if it crashes. For me, profiles are rather important, when the screen is off I want to limit it to like 200mhz or something.
i figured out why SetCPU makes my phone never wake up, the settings i was using was ondemand 100 min 1000 max. SetCPU is set to 100 in standby and this is just too slow and puts the phone completely to sleep.
ive since moved up the phone to 400 min and ive gone a day without any sleeping.
and SetCPU works fine on my phone, and a few friends who have the phone aswell, this was our only problem, and i dont believe it was a problem, its just the way the app is designed, to give full control, leaving the only room for error on our hands..
but still an fyi would be nice lol.. i read the entire huge description of SetCPU, like a half hour read
Try setting the scaling to 'ondemand' or 'performance' if it was set to 'conservative' as default (mine was).

Logs can be done by getting the Log Collector app from the Android Market. Or, you can plug it into a computer with ADB and run:
adb logcat
I'm interested in the FC crash and why it works for some and not others.
Thanks
In fact, everything seems to work for me too....
I'm especially interested overclocking this thing, as it's the 45nm ARM CPU released in an Android phone en masse. I might get myself a Vibrant if it gets rooted.
The whole problem is that the default is conservative... changing it will cause phone to freeze.

Then change the Freq Step in Advanced to 100%, should have the same effect as ondemand.

This will fix it not waking? Is this better than making the minumum to be 400mhz?
When it was not waking, I changed all the minimums to 200mhz, but it was still dropping to 100mhz? Why would it do this?
With my phone rooted didn't work on first install, whenever I launched it, it kept crashing so I uninstalled and installed back and it works perfect
I went through the whole resetting to factory defaults several times until I determined not coming back from sleeping was setcpu.
I do not think it is a crash problem.
I had the scaling set to ondemand.
Do we know what the minimum CPU speed is for the samsung? I had it on 200 and still had a problem. If I have min at 400 is there a point in using setcpu, because the existing OS will scale for us?
I really loved the product, but I need to feel like we have a more confident answer to this problem.
Kudos to coolbho3000 for a great product. For the avoidance of doubt, I purchased the product.
I'm having a lot of trouble with this app too...
So I'm returning it until someone can post some settings that work flawlessly
So no matter what kernel I use, when ever i use SetCpu (or overclock widget) to underclock my phone when the screen is off it causes the phone to freeze and I have to pull the battery out. I set it so that it goes down to 200mhz, tried 400mhz and experienced the same problem. Any ideas? Solutions?

It means that there is not enough voltage run that frequency on your phone. Some times these kernel developers undervolt the phone which all phone don't support at all. Try some other kernel like the xtreme kernel. That kernel actually work for me and I can underclock my phone without freezing.

wow.. i just posted something like this i had set cpu installed since i rooted my phone last week. today i was playing with the settings because my music was stuttering.. i thought it might be a underclockign problem so i changed the profile to "ondemand" it made the stuttering better and everything seemed fine. about 12 hours later i got home and was playing with the phone. i updated 3 programs in market and all of a sudden my phone would go to sleep and not wake up. had to do a battery pull. i uninstalled the 3 programs i updated but the problem kept going. just uninstalled setcpu. hopefully it resolves everything

The use of profiles is not recommended on Galaxy S phones. The developer of SetCPU actually does not recommend using any other governor than conservative, even though we've been able to make Interactive work on some kernels.
I'm running Baked Snack 1.3 and found it to be stable at 1.2ghz using OC Widget. With screen on I have it set to min 400 and max 1200. With screen off it's set to min 400 max 600.
I too am having this problem. No mater what rom or kernal I use. It seems as if Setcpu and Overclock widget sometimes cant read the frequencies and let the phone underclock to 19.2Mhz which is probably like trying to wake the dead!
I wonder if it has anything to do with the new Superuser.apk? it always seems like setcpu is trying to get permissions. Maybe, I dont really know. Can one of you really smart people look into this?
In the meantime the only profile that I have set is screen off Max 800 Min 400, maybe that will work?
same issues here. i'm running with my screen off at min 100 and a max of 800. If i change my max to anything lower, my phone won't wake up. I'm running the latest VIPERrom. I'm hearing some mixed feedback about this app so i would like hear your feedback.
What i've gathered over the last several months, is that SetCPU profiles are buggy with our phone. Its recommended not to use profiles.
I'm fairly certain that SetCPU should not be used without a custom kernel that allows for over/under clocking. If you're on the latest ViperROM then you are using a kernel that we have no source code for, therefore it doesn't support over/under clocking; rendering SetCPU useless and prone to cause problems.

If you have it set to under 200 with the screen off it won't wake up after a while.
I've had the same problem on all builds and ROMs that I've used. The only constant through all the different setups I've used were Advanced Task Killer and SetCPU. I stopped using ATK (with auto-kill on screen off, I use EStaskmanager for manual killing when phone is on) and the problem seems to be mostly fixed. It does still happen once in a blue moon though, say once every day or two.
Phoenix Kernel/Syndicate ROM 2.1
SetCPU: 100min/1200max
Screen off: 100min/200max
Batter < 30%: 100min/600max
Hi all, not sure how to address this, but my battery's been a little crappy lately. I downloaded SETCPU after not using it for ages, and I noticed when i set it that my CPU seemed stuck on the fastest speed. Downloaded SeeCPU and confirmed. So though my min-max is set at 245-986, it's always on 986.
I'm using Kushdeck’s latest w/ the stock kernel (which is the cyanogen kernel), and I even went so far as to wipe all data and re-flash everything...still no luck. Any ideas on how to proceed?
Did you disable the perf-lock in setcpu?
We're comin from a pure power source.
Yes, perflock is disabled. I can lower the cpu speed, but it wont scale. So the default is 998, and typically I'd set the min/max at 245/998. I noticed that the CPU was always at 998, it never scaled down. Now I have the min/max set at 768/245 and it's always on 768. If perflock were disabled I thought I wouldn't be able to change the speed at all, though I may be wrong there...I also tried the perf unlocker in setcpu and it reports that it is already unlocked.
At this point I wiped data, cache, and Dalvik. Re-flashed the rom (deck's aosp rom) , stock kernel, practically no apps installed except setcpu and seePU to monitor usage.
Oh and the governor is the default, I think interactive...
Try another governor like conservative and see. After that I'd try another kernel or download the stock one again in case something is buggered in yours

Thanks already tried a different governor, tried a tiamat kernel, then said screw it and reinstalled the rom from scratch. Still having the same issue. I may go back to a sense rom to see of that makes a difference.
Hi, I know and understand what problem you're having. I had this on my desire. Run a ruu or flash a pb99img. The problem only happens on non sense roms. This is the only solution to make non sense roms work. Just try it. Good luck!

I ended up flashing back to Myn 2.2 (which is Sense) and it started working again. Thanks!
I tried to search for a thread relating to this but couldn't find anything, if anyone knows of one a link would be appreciated.
OK, so I flashed Motleys kernel 2 days ago. Everything was running fine, I had it OC'd to 1.6 and it was super fast and smooth. I had set the governor to "on-demand" to try and save some battery life(over "performance"), and also because it seemed like the CPU would run at full 1.6 constantly if it was set to performance (I don't know if that's how it should be or not, but this isn't the issue). I used System Tuner to OC it like he recommended in his thread.
Yesterday I set it to performance to run some benchmarks, and then continued using it on performance to see how it felt. About an hour and a half later I also started messing with my home screen and apps and ended up accidentally using Quick Boot to take me to the bootloader. After powering it back on I checked System Tuner to set the governor and once I did I noticed, according to System Tuner, that 2-4 of the cores are running at full 1.6 and the CPU usage is from 25%-100% even though I have nothing open.
I flashed my recovery via Clockworkmod Recovery, Motleys kernel is now replaced by the stock kernel, however I'm still having the same issue, but just at 1.3. Any idea why the CPU is running so high, for apparently no reason?
.....
OK, so I just checked System Tuner again and the CPU doesn't seem to be doing as bad now, but it's still all over the place and I don't have anything else open. Here are the times:
Offline - 77%
340MHz -11%
475Mhz 1%
1.2Ghz - 5%
1.3Ghz - 1%
Compared to yesterday when it had said 1.3GHz 79% or something like that (and was running nothing but system tuner).
So, yeah, that does seem a lot better but one thing remains; the CPU usage still jumps up to almost 50% and once again, I am running nothing but System Tuner, so something still doesn't feel right.
I think ondemand governor is causing the CPU to shoot up so often and quickly.(That's all I can think of.) I always use interactive and it's usually the preferred governor. Ondemand is more for people who play lots of games and they need the extra boost. If you game a lot then I guess you should still to it.
