I have been flashing CM7 nightlies for a while now, but in the last few versions (currently on #12) I am starting to see more random reboots (and occasional boot loops). I am using the stock kernel. I have experienced the problem while using the stock adw and LPP.
I had been flashing over just clearing cache and dalvik, but recently did a full wipe to see if I would still have the problem, and I did.
These reboots appear to happen when I am browsing the internet (stock browser), listening to audio (stock app, pandora, or audible.com app), and playing games/downloading something all at one time.
I am not overclocked at all, I am using all stock settings in CM7.
Any instructions on what can be done to fix/avoid this would be great.
I would lean towards it being a CPU issue, It may be that the new CM7 Kernel is slightly undervolted and when you are using the CPU for an extended amount of time that it reboots on you. I suggest trying out some other kernels to see if it continues to happen the new incredikerenel is supposed to address some of the stability issues people have been having lately.
Thanks, I will give the new incredikernel a shot and post back.
Edit: So far so good. After installing the 3.6 incredikernel I have not had any random reboots, even under pretty heavy load. Thanks again for the tip.

For some reason, my phone will not run a kernel with HAVS on it. Some kernels boot loop at the evo 4g screen. Others load up, only to experience random reboots every few seconds. I've tried wiping everything several times, flashing rom and kernel at the same time, flashing rom then kernel after reboot, etc. Also, this happens with or without SetCPU. I've searched the forums, and have also asked on one of the kernel forums, only to get the answer "some phones just don't get along with HAVS." Any other ideas?? Anything I can try?? Thanks in advance.

I have the same problem. I pretty much haven't been able to get a kernel to work correctly after CM6 RC2. I've tried many different versions of the snap kernel. Pretty much none of them work. I have gotten away with a few custom kernels working, but normally I will get at least 1 random reboot per day with them. And they're from August. I don't know what it is, stock kernels run fine; however, I haven't been able to get CM6 to even boot for me after RC1.
I don't seem to be having any kernel panic. k_lastmsg isn't even there after these Cm6 boot loops.
I really hate sense, so I have been running Emerald mod 1.1.1. It's the closest thing to CM6 right now. It works because it's using a kernel that can't OC, and only has 2 touch points.
I have a few k_lastmsg files, that explain the random reboot. These are from snap kernels. I can't get any useful information out of them.
It's possible the minimum possible undervolt with the HAVS kernel is set too low for your particular phone; some phones can be really picky with how far they can go.
Do you live in the south? Are your normal room temperatures above 85F?
Are your evos getting too hot?
No. Temperatures here have been around 60. I don't think it's over heating. I was able to boot a HAVS975 kernel. The kernels that have higher voltages seem to boot, but are not stable. However, anything under 900mv cause boot loops. This was on the latest CM6 nightly. It booted, but 3 minutes after I got a random reboot.
I just flashed 8 kernels over CM6.0 final. The only one that actually works for more than 5 minutes is SnapV2. I can get 5 of them to boot. The rest loop. 7/8 result in a random reboot after about a minute or so. I can post some logcat logs. If anyone can help me decypher the actual problem, it would be great.
Hey guys, I constantly have random hot reboots. No pattern or anything, it just happens. I have asked a few guys in Calkulin's forum... everyone offered help... but no one actually helped me fix the issue.
Basically, I am on Calk's 2.0. Only other thing I flashed was Overstew's ICS theme (I used themeporter). No, my issue isn't the theme. I have had these issues since Calk's 1.5. Theme or no theme.
Here's my routine of setting roms up:
Manually wipe everything -sd card.
Use Calk's Format All.
Flash Calk's 2.0 and Overstew's theme.
Reboot.
Install Titanium, but only restore apps (41 apps), no data.
Set LauncherPro as my default launcher.
Setup my settings.
Just using Calk's stock battery saver script. No overclocking or undervolting.
I have tried wiping and new downloads several times. I wiped my external sd card. I even removed it, for a while.
Any ideas? I had a logcat during the hot reboot too. It had some errors around GPS right before it rebooted.
Thanks
P.S. I also had the same issue on my old Evo 3d. I just thought it was my hardware...
Undervolting is what Calk himself recommends to fix hot reboots. It's in the OP on his ROM threads. Also different kernels. Tried any of that?

Actually, he recommends restoring the Stock Voltages to remove the default undervolting.
"Having random reboots or freezes?
Try flashing the Calkulin's_Undervolt_Stock_mV_Settings_for_E4GT zip attached or flash a different kernel
first thing that comes to mind is the viper los script
I don't have the Viper LOS. I have tried different kernels. Plus, isn't 2.0 using Rogue's stock anyway?
I'm not undervolted. 2.0 can't be undervolted without using tegrak :/ all great suggestions... it's driving me insane that I can't figure this out.

I am on Calks 1.5 rom and do not have any reboot issues. The first thing I do when I flash any new Rom is put back the stock pulled kernel and I believe this is the most stable of them all and I also have never seen an LOS on it.
Do you have any battery saving apps or task manager apps running? I know these have caused issues like this as well...
No. Nothing! I had stock pulled kernel before. Maybe I will try it again. But isn't it the same as Rogue stock + boot animation and init.d?

I used to have random reboots with different lockscreens from the AIO mod. Had no lockscreen and had no reboots.
Definately recommend stock kernel and restoring stock volt settings. As for Los, ek02 fixes it
If I was helpful, give thanks

Hey I remember chatting with you in the Calk rom thread. "OP"
As a update to my situation. I was also having random hot reboots on EVERY rom I was on UNTILL my latest combination of Kernal / Rom.
My current setup is Kernal: EK02 and my rom is Calk v2.0 which is built on the EK02 stock build.
I have yet to have any hot reboots. My current Up Time is 38:58 which means I have not did a battery pull or reboot in 38 hours.
I also use Titanium Backup to restore about 30 apps + data on my end, and MyBackup Pro to restore bookmarks / texts
For the first time it looks like my hot reboots are currently fixed. I dont use any undervoltages and no SetCPU no custom launcher and no custom lockscreen. Everything Stock and all 7 home screens nearly filled with icons and picture frames ect...
I was using Rogue's kernel and was going to switch to stock today, as that was the only thing I didn't do... but I was in the middle of calibrating my battery this morning and I was getting great battery life. Well, 15 hours later, not one hot reboot, light usage (lots of texts through google voice and xda, and a little browsing) with a screen on time of 1:45 and I'm at 54%. Has my issue been fixed? I have no idea. Am I happy at the moment? F*ck yeah.

After jumping to the EK02 Rom and Kernal Im also a happy camper now.
No reboots / No los / No lag / No dieing battery.
Now if only Sprint could fix there slow 3G that be great.
On the topic of battery, I never calibrated or did anything special but I noticed my phone can last 12hours + without charge if I turn off 3G when Im not using it. For example I work in a warehouse where I get good signal for calls and texts but 3G is mad slow, so I turn 3G off but am still able to recieve texts and calls and my battery life doubles in that period of time. Soon as I turn 3G back on, battery starts to die faster.
Whenever I play a game, whether it be Temple Run, or Fruit Ninja, my framerate drops to around 30 (rough estimate) whenever I touch the screen. If I don't touch anything, it runs perfectly, around 60FPS. I've tried re-flashing the ROM and Kernel multiple times, and letting it settle for a few hours before trying, but I always get the same result. The lag doesn't seem to happen before I install any apps, but an Android phone without apps is a bit pointless. I'm hoping that there's another cause to my problem.
Does anyone have any idea what could be causing this?
I'm running AOKP Build 34 with Franco's kernel, Milestone 3
Stock CPU values
Stock ICS Launcher
Changing the CPU governor does nothing to alleviate the framerate drop
Thanks for any help!

When last time u.have done FULL wipe? If been awhile u should,i have same setup and its running perfect
I always do a full wipe (wipe cache twice, wipe system twice, and wipe data twice) before installing new ROMS. Could it be because I forgot to wipe Dalvik? Or is that already part of the cache partition?
EDIT: Apparently, the cause of the lag was the "Show touches" toggle, in the developers section of the settings menu. It doesn't lag on my Skyrocket, so I'm a bit curious as to why it lags my GNex. Can someone else verify this?

Ok I have gsm Gnex with AOKP jelly bean build 1 with Franco kernel overclocked to 1.4 GHz and I am experiencing a random reboot problem starting today around 1 am.
I do have cpu undervolted, but it was undervolted for some time now, but just to make sure, I increased the voltage just in case. No luck.
Next thing I though that might have been a problem is the fact that I dirty flashes the AOKP build 1 from the nightly of AOKP, but I flashed it for a time now and never had that problem until today.
Another thing I changed is that I changed the boot animation from AOKP one to cyanogenmod 10 one. That, I flashed yesterday.
One thing I do like to mention is that I think there might be something to do with SetCPU profiles, because I set the profiles so it underclocks when phone screen is off or if the phone cpu or battery heats up, and one reboot was when I was unlocking the screen and another one was when I was watching youtube, and the third one was when I was playing a game, which heats up my phone. The thing is though, I have set those profiles since day 1 and never have encountered any reboots until today
Can anyone help me? Is it something that I should care about, or something that is temporary? Any recommended actions? I hate factory wiping, so that is the last thing I wanna do. Thanks in advance!

Tough one. Myself I'd start off by disabling all OC/undervolt settings & disable SetCPU profiles. If that doesn't resolve the issue, temporarily flash back stock kernel.

For some reason, when I cleared the cache and dalvik, It doesn't seem to reboot anymore. But if it ever happens again, I'll do what you told me
Thanks!
Hi, this happened again today, but I noticed that it isn't a full reboot. (no Google splash screen)
Any ideas?

I've had this E4gt for a few days now. First thing I did was root it with the FI27 Odin one click method, then install Agats source 6.5 kernel. Had some random reboots that I shrugged off as my phone not liking any undervolting. But it still does it, even under _dan's lightweight v0.2 rom
It isn't completely random though. Most of the reboots are when I'm trying to wake up the phone after letting it sit idle. Other times it'll reboot while it's sleeping idle. it has NEVER rebooted during use (I ran pandora/poweramp for 8 hours no problem)
It also occurs under most governor settings.
It almost seems that for whatever reason, idling at 200mv is causing the phone to crash and reboot.
the only overclock utility I use is System Tuner Pro, however I don't know if this could be the cause.
Only other option I can see is unroot/flash stock FI27 and see what happens, but I really don't want to go through the hassle, especially having to get another effing phone (since assurion can't be bothered to ever send a proper working phone)
bit of info on my phone I guess
Rooted it from bone stock factory FI27 using Odin FI27 One click rooting (success on first try)
Agats source 6.5 kernel
_dan's Lightweight v0.2 rom
Ktoonservative kernel (however it seems every kernel does this)
Scheduler set to noop
no oc/uv settings currently
I use System Tuner Pro to adjust clocks/governor settings, etc however, I haven't done many tweaks besides my OOM settings.
Stock rooted with Agat's source 6.5 was causing reboots as well, under the same conditions (deep sleep reboots, and waking from deep sleep)

Is the phone new or did you acquire it used? I had random reboot issues...tried numerous software fixes (new ROM, new kernel, uninstalling apps). Finally found the problem...a faulty power button. The solution for me was to replace the phone under warranty.
Its an assurion refer. According to the phones lifetime stats however it wasnt used for more than a week or so in august.
Also its not the power button. I watched it lock up and reboot earlier today
I'm almost thinking I should call asurion and tell them they sent me another effed uup phone and demand a nib phone. But that means unrooting this one and I'm not sure how big of a pain that will be

Ktoon... gov gave me some odd results too, try pegasusq and don't under volt until you have established a stable setup.
Honestly though try a different rom, FI27 seemed buggy to me but FI03 was alright. If you want to try Jellybean then give Codename a try. Its been rock solid.

Interesting that you would mention ktoonservitive!
My setup has been always dead stable. But....
I've had a few random reboots when on calls lately and have been running that (ktoon..) for a little while now.
I'll have to switch that out and see what happens.
Well im currebtly running the latest version of recaulk so ill report back with my results if i gwt any reboots.

After running Re-Caulk all night, I've come to the conclusion that FI27 was the culprit.
Ktoon probably wasn't helping, as I was running it quite often.
I'm using whatever kernel comes with re-caulk, min at 100mhz, max at 1400mhz, -25mv. Battery life is better than before (though, with my 3800mah battery, its already insane)
buttery smooth goodness too
Bit of an update since I made this thread.
Running smartbench 2011 I was getting abysmall productivity scores, and it seemed overall my scores were AWFUL no matter what in any benchmark (overclocking to 1.5 would barely get the almost to baseline numbers)
I called asurion and told them I was having reboot issues with the phone etc, they sent me another refurb today.
Scores are exactly as they should be now. Productivity scores in smartbench 2011 went from 2500-2800 to 4000+
I think the CPU on my first e4gt had a problem with the processor, which is why deep sleeping was crashing it.
I do realize benchmark scores mean nothing in terms of real world performance, but when there's a known baseline number for a particular phone, and your phone is struggling to even get close to that baseline (even with a maximum overclock) there is clearly something wrong with it.
