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.

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?

More info.. What rom are you running? Are you sure your rooted? What settings are you applying?
I have not had any issues yet with setcpu and my screen being off

I'm running Baked Snack 1.1, doesn't matter what rom or kernel I use though, it still happens.
It doesn't matter if I use overclock widget or SetCpu, if I were to set it so that my phone underclocks to 200mhz or 400mhz while the screen is off it freezes and I have to pull the battery.
Same here im running stock and i've tried setcpu and no matter what i hav to pull the battery out everytime. So i uninstalled it.

I had the same problem set the cpu with min of 400 and max off 800 should fix your problem

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.

My SetCPU is using conservative and I haven't had any problems so far. I am running BonsaiROM 1.14.

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
I've got a problem with my I9000, several times throughout the day it will randomly restart itself. It will be quite happily sat idle in my pocket not doing anything, and then suddenly I hear the boot-up sound from my pocket. It's just started doing this since Thursday or Friday I think it was, had nearly 700 hours uptime on it (699 hours ) and then I noticed from my SeePU notification that something was hammering the processor, running it at >90% for more than 10 minutes. Couldn't see any programs running in the background so decided to restart the phone. This is one my problem started.
It's running stock JPY with Voodoo Advance kernal, it was overclocked to 1.2GHz and had some undervolting from 800MHz down, this had been stable for all of those 699 hours, but I disabled the OC and UV yesterday to see if it was that causing the trouble, but even with it disabled the phone's still been restarting.
What would be really great is if there is some kind of crash log for Android (something similar to the Windows Event Viewer) so I can see what's causing this. Does anyone know if such a thing exists, and if it does how I might go about accessing it?
Failing that, anyone know why my phone would suddenly start restarting itself now?
had pretty much the same issue, different kernal and rom... but had an OV/UV that for the most part was stable...
then today was continually restarting.....
solution?
changed CPU scheduler to noop
changed CPU Governor to conservative (Galaxy S cpu default configuration)
Now not restarting at all... and that's with a 1.3GHz overclock... running several benchmarks and no undervolting at all.
I'll let you know if it starts acting up... but interesting that this at least fixed it for me.
Stupid thing has restarted itself twice this morning. This is ridiculous.
I've just set the schedular to noop, can't see an option to set the governor though. Will see if that sorts it.
Would really appreciate knowing if there's a log file or something though
If it was a PC you would say its overheating .
jje
Found an app on the market called OS Monitor that shows all the running processes and what load they're putting on the CPU, it also shows the dmesg and logcat log files.
Thankfully my phone hasn't restarted itself since changing the schedular, but if it does I should hopefully now be able to find out why
quick answer. Reflash the phone .
I guess reflashing and removing some dangerous apps will be good for you phone.
Hmm, well looks like it's given up on restarting itself and is just plain turning itself off now.
Looks like I'm going to have to reflash the stock kernal and see if that fixes it
Just as the title says, but here's some more details.
I have my cpu set to 1.1Ghz during the normal day 245Mhz min.
I have my widget on my homescreen and a custom profile set for when the screen is off for 368max and 245min.
When I turn my screen on and unlock it, it lags on my screen and says 368 max, then it jumps to the 1.1 and everything is fine.
It seems to lag there longer than it used to, has anyone else noticed this problem.
I used to have Pershoots Kernel on 6.1, do you think if I put Pershoots Kernel back on it will eliminate the lag and switch to 1.1 faster than it does now?
Just some thoughts and advise would be great, thanks guys.

I would ditch setCPU and use CM's built in overclocking settings. set your clock speed to whatever you like and use the ondemand governor.
your screen wake lag will almost certainly disappear and I bet your battery life doesn't change a bit. you can play around with it, of course, and find what's best, but I have found that since CM introduced built-in overclocking, it is more functional to use it instead of setCPU. my battery life hasn't changed a bit, partly because when the phone is in an idle state it is underclocked by default, and also because I don't have setCPU constantly having to think to make changes to my clock speeds and governors based on what profiles I've set up.
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.
Hi everyone,
Thanks for reading this . As specified above, my phone has a rather serious problem of overheating. To try and reslove the issue I tried modifying the CPU frequency, to set it low enough. And a very bizarre thing just happend.
Opening Kernel Adiutor, I saw that 4 out of my 8 cores (the 2.5 ones) were running normally. No overclock, stock settings, stock governor and so on. The issue seems to be in the other 4 (the 2.3 ones). Both the minimum and highest frequency allowed is set up to the same parameter (1556 mHz), forcing it to stay at maximum clock all the time. I tried modyfing via Kernel Adiutor the settings, lowering the minimum frequency allowed to stock one (which should be around 300 or something), but it had no effects: it immediatly comes back to 1556 and just won't come down.
All of this started happening after i removed Franco Kernel from my system, flashing another ROM (Chroma) with a different kernel altogether. I'm currently on Cataclysm ROM and after doing a clean install, formatting internal storage as well as every other partition, i couldn't resolve the issue. Moreover, Kernel Adiutor sometimes won't even show my CPU settings, stuck on an infinite loading. If anyone could help me, it would be much appreciated. It's really important. I'm by no means Android expert but i do have a rather basic understanding of ADB and so on.
Thanks a lot for your time.

I used to own a n7 and that allowed me to set min and max freq. with apps fine but i am also seeing this on my 6p, i don't notice any "overheating" although it may be due to me being used to it always running hot since i run a lot of heavier programs and also you know... SD810 but i guess it does the frequency thing as a way that frequency is actually controlled on this platform or something, because it sticks fine to the limits you set while flashing a kernel but no app can get it to stick. Then again this is just me sharing my experience with it as it is my first phone with this platform, so maybe someone who knows more about this could offer some help.
