Currently running VillainROM 10.3.0 (with Sense UI)
Does anyone get problems regularly on the slightest of underclocking (using SetCPU)?
Min at 245:
- Alarm wont turn off (only snoozes)
- Clock on Lock screen wont update
Min at 128:
- Music player becomes stuttery, took a few minutes for screen to power on to turn off music
Noone else seems to have mentioned it ?
Am I doing something wrong?
And its a bit worrying considering so many custom ROMs come pre-clocked.
Totally a hardware issue. Your phone just can't cope with the lower speeds. Not all can.
Mine will do 19mhz on sleep and wake immediately etc. but most others won't
Villainrom should default to the stock settings unless you install something like setcpu and define oc settings.
Not sure about other roms but I guess they do similar unless otherwise stated.
ah cheers.
i knew that some phones couldnt reach a particular Max clock speed, but didnt know it was a similar case with the Min clock speed too
You should try Cronos Droid. I am having the exact same problem as you on all OC'ed 2.1 roms, except Cronos Droid.
My settings on Cronos:
Screen on: 710 mhz
Screen off: 160 mhz
I've been having some pretty interesting reboots with my Atrix.. they are random, but usually have something to do with spotty service. Sometimes the phone will get really hot and this will cause a reboot, even if i have a temp profile set with setcpu. I honestly don't think the temp profiles work correctly with setcpu. I tried setting a screen off profile set to 456mhz also to maybe clock the processor down to prevent it from getting hot but it didn't help at all either.
I'm currently running Neutrino 2.2GT based on CM7 weekly #6,with faux's 023r kernal overclocked to 1300mhz not uv'ed at all and i'm running the 37p radio.
I've tried flashing a new kernal, full wipe/reflashing Neutrino multiple times, dunno if this is strictly a hardware issue with my phone but has anyone else experienced anything like this?
EDIT: i actually just ran speedtest.net and had a random reboot once during upload, and once during download. i also just changed my apn settings to the default ones posted here: http://forum.xda-developers.com/showthread.php?p=22624940&mode=linear&styleid=16#post22624940
Since upgrading to KitKat, my phone will reboot (not instantly - after some time) whenever I use any governor other than interactive.
This is with any 4.4.2 ROM, even after full wipes..
Anyone else noticed this with KitKat? If you want to test - please change your governor to ondemand - use your phone normally (may take a while) but after some time the device will freeze and reboot.
Is this normal? Upon restarting the governor will revert back to interactive
Any advice will be much appreciated folks.
Mine does the exact same thing with ondemand governor no matter what rom I'm on. I thought my phone is just messed up. You are the first person I've heard has the same problem. I really don't know why its like that?

same here
I am currently running 4.4.2 stock with BeastMode kernel from freeza and the ondemand governor causes stutter and a reboot after a few minutes of using the device.
As I recall, this also happened on the stock kernel.. the interactive governor appears to be more stable, but it does seem to take a greater toll on the battery.
No matter what voltahe settings(+/- 100mv) I use with the ondemand I keep getting the same results.. weird
By chance is knox included in these roms?
I had the same problem on stock where phone rebooted constantly, tried everything until I fully uninstalled Knox and it has since stopped.
I always have my CPU governor set to ondemand.
I am running stock on my note but have deleted everything concerning knox on system/app. The problem still persists...
Hmm that's really odd.... have you tried using link2sd and searching for knox just in case it left anything behind? Providing you are rooted.

I just tried that and no knox to be found... I do not know if it has to do with the "silicon lottery" in which OC and OV doesn't play well with some governors. .
Anyway I stuck with interactive and it has been solid so far... my major concern now is fixing that persistent "Cell Standby" battery drain that persists even on airplane mode.
SO... in regards to the KT-SGS4 KitKat 4.4 TouchWiz kernel, the vast majority of users seem to have no problems with it, but there ARE KNOWN issues that appear to be caused by this kernel for some users, with varying degrees of rarity. WHY certain users have these issues when others do not is not currently known, but it would be great if we could figure this out. I am HOPING this thread (and it will only be a THREAD with input from others) will help us find cures for the issues we face with this kernel.
KNOWN ISSUES:
#1. Sound skipping - This seems to be the most common issue experienced with the kernel and I actually would not call it rare. Some possible fixes for this are to: A) increase the Media/Music Min Mhz and Bluetooth Profile Mhz to around 702 Mhz or so, B) try using a different I/O Scheduler and try adjusting the Internal and External Read Ahead Buffers, C) change disable_hotplug_media from a 0 to 1.
#2. Phone freezes/locks up while charging
#3. Screen flickers when a window is open over the desktop
#4. Mobile connection/data (and possibly also GPS) loss a while after booting phone - this may be the rarest issue, but it is OBVIOUSLY the most serious. I have suffered from it personally. I contacted Ktoonsez regarding this and he denies it being a known issue since many thousands of users use his kernels and don't have this issue... I have confirmed multiple other users who DO have this issue and the only thing I see we have in common is the KT-SGS4 kernel. It appears that this issue MAY be fixable by using the "right" choice of governor and settings. The problem is that what the "right" choice of governor and settings are MAY be determined by your ROM. On stock rooted NAE with MF9 bootloader, using largely the kernel default settings, including the interactive governor, APPEARS to have cured this issue for me (as well as the freeze while charging), while using the ktoonserativeq governor or the pegasuq governor appear to have caused this issue (I am still in the process of investigating this...).
This is not meant to be in any way negative towards Ktoonsez and I certainly appreciate all the work he does to provide us kernels, but there ARE issues that some of experience and I hope this thread can help us work TOGETHER to solve them! If there are any other issue that you believe should be listed, please post them. If you have any possible cures, please post them. If you need any help, please ask. If you have any input, please post! :highfive:
I can't get his kernel to run on my phone for the life of me so I stuck with Negalite NAE Stock Kernel, but I use his kernel religiously on my wife's s3. Even using basically the same setup I still get skipping on music, phone goes unresponsive after charging a few hours. And a few others.
Is music skipping only for users who are also trying to do ViPER4Android (probably with Convolver turned on)? I think the governor and adjustments are also critical in solving this problem. I've been using ondemand and somebody said interactive is also helpful. The other thing here is that it could be an issue of I/o scheduler. I've been using sio. I'm getting minimal skipping at this point. You're right that ktoonservativeq caused MAJOR skipping, even with tons of governor tweaks.
After switching to ondemand, my phone hasn't locked up while charging, but it has randomly locked up at other times. Weird.
On issue #4, I've lost data less with ondemand but it hasn't completely solved the problem. Sometimes I can toggle Airplane Mode on and off and get going again, but mostly that toggle won't even work and I have to reboot.

That is an interesting question, now that you mention it. I had been using ViPER4Android, probably while I was having the skipping issue, but I stopped using it in the long process of attempting to cure my mobile connection issue (I read something that made me think it could be related) and I'm actually not sure if I ever had the skipping issue without it.
Of all the issues though, this one is very common in the KT-SGS4 kernel thread, so I DOUBT (but don't know) that everyone experiencing it is using
ViPER4Android.
(Also, I THINK it skipped for me without Convolver turned on).
I haven't used v4a since I was on Negalites

Yeah, I think the skipping has to do with the kernel generally allowing the governor in default settings to throttle down too low when music is playing...

Don't forget the issue where the phone will not power up while charging if it's charging while off.
I don't. Mine even skips while the screen is on and I don't use V4A and have tried other than stock music players as well. I have no such problems with Nega but I've tried different modem firmwares too. These don't seem to affect this problem.
If anybody wants, though, they could chime in on my Wifi tethering problem. Nobody seems to wanna tackle it.

I didn't forget it, it is issue #2!
#2. Phone freezes/locks up while charging
In my experience, the phone does NOT have to be off while it is charging to have this issue, it would happen to me when I was charging my phone with it on. Fortunately, on NAE stock rooted with MF9 bootloader, using the mostly default kernel settings with the interactive governor seems to have fixed this issue for me, as well as the mobile connection/GPS issue (knock on wood still...). I mainly just adjusted the I/0 Sceduler to noop and the Media/Music and Bluetooth Min Mhz to 702 Mhz from the stock settings. The only issue I am personally left with now is the screen flicker.
I don't think the screen being on or off relates THAT much to the music skipping issue, it skipped for me too with the screen on. Definitely I would say, using the ktoonservativeq governor with Ktoonsez' settings WILL result in music skipping... BUT, IMO, this MUST BE TAKEN INTO ACCOUNT, Ktoonsez DOES NOT HAVE OUR PHONE... how can his settings POSSIBLY be OPTIMAL for our phone? Think about that!
As far as your WiFi tethering issue, I am well aware of it personally, having read your other posts, but I don't know much about this (don't use it myself) and in another thread I was going to direct you to a link you are already aware of that didn't help. If anyone can help arikdahn with this, please jump in! :good:
I definitely had more problems with music skipping when the screen would turn off. Using ondemand or interactive with sio and 2048 read ahead caches seems to have almost completely resolved the issue for me. I'm still not sure which I/o scheduler is best.
I would think that the governor throttles down MORE when the screen is off, which is why I consider the Media/Music and Bluetooth Min Mhz settings important to be set above the default, which I believe is Min and should override that throtte down when music playing (ay the expense of battery time, but the battery is meant to be USED when needed) and I can't see how that CAN'T cause skipping in most setups. But it does occur for some even with the screen on.

Well, all I have to go off of is my own expertise with MY equipment only. My thoughts based on this is that it's not a limited-resources type issue, like if the CPU's throttling down or not buffering ahead enough or whatever. I had skipping problems all the time and I tried it with uTorrent running in the background, items downloading/moving, and these processes didn't slow down or cause any problems themselves. That's why I think what I think. Anyway, what this means to me is that I do not believe that in my situation, anything I can do with the kernel's configurable options will change anything. Then again, i think my phone's possessed anyway. It won't run the dialer on AOSP/CM roms and might just be one of the most finnicky high tech devices I've ever owned.

Hey, I'm not in any way disputing what you are saying, the point of this thread is to figure these things out! I'm certainly not presenting myself as the expert on these issues! I'm just a lucky one who seems to have mostly resolved the issues on MY phone. (BUT... I AM NO ANDROID EXPERT EITHER and will never claim to be, but I am not saying it is a limited-resources issues, what I am saying is that I believe the default settings will allow the governor to throttle down to below the level necessary to play music without skipping... I could be wrong, but that it what it looks like to me.)
Because SO MANY people APPARENTLY don't have MOST of the issues mentioned, I personally think this is highly related to which ROM you are using... though I don't know what ROM those other people are using...
When i woke up today trying to turn off my alarm, i noticed that the phone is choppy and lagging heavily which is very unusual. Initially i thought some apps are updating but this lagging never stopped. So i used the system monitor in FKupdater to check if the cpu is running high, but instead i found out that the disk i/o is constantly running at full. I did some findings and currently there is no per-app disk usage monitor so i don't know what app is causing this. My phone is almost unusable now, can anyone help me with this?
My Nexus 4 is running on older version of ParanoidAndroid which is 3.69.
Android version 4.2.2, and latest franco kernel.
