Known as the "Sleep of Death" (SOD). I see you're on Siyah. Are you overclocking or undervolting? Common cause is using undervolt values that are too low. If you are undervolting, you may need to bump your voltages up a bit. You can also change your governer to see if that helps.

i have not touch an voltage settings, i only changed the governor to "lulzactive" with SetCpu
but the problem only started to occur very frequently like at least twice a day since i updated to ICS (but the first few days were fine, only this 3 days it started). when i was using GB, i had this problem only 2 times.

Hmm... try a different governor and see if the problem persists, or reduces in frequency.

Just post here. Not sure how much more help I can be though. If you haven't messed with clock speed or voltages, then governor is about the last idea I've got. If that doesn't fix it, try going back to a stock kernel.
Then I'm all out of ideas.

No problem. Curious tho, when you updated to ICS, did you also update Siyah to 3.0 or higher? GokhanMoral compiled a v3 for ICS.
Happens sometimes on cm9 but pressing home key for 5 secs walked the phone up

ahhh icic, well will try it out next time the SOD occurs to me again
when i was using setcpu on GB i got SOD with lulzactive too, i didnt under/over clock.
i just use on demand or conservative instead,i have not bothered to find out why it occurred

I just installed the new Siyah 3.2b1 kernel to run my ShoStock 2.2.2 ROM last night and everything was working fine. I didn't make many changes other than switching the governor to lulzactive and the i/o scheduler to noop.
It was running fine over night (lost 0% battery).
Then today after I used the phone for a few minutes the battery seemed to drain a little quicker. I know its too early to complain about battery life but I decided to investigate. When I checked cpuSpy it showed that all of the frequencies were barely used (mostly spent in deep sleep over night) but the 1200 mhz frequency was used most after that (significantly more than the others). When I went back into voltage control (same thing with setcpu) I noticed that it seemed to be stuck at 1200 mhz. The only thing that fixed it was changing the governor.
Does anyone have any ideas on whats causing this and how to fix it (I had great battery performance on lulzactive before so would like to use it again)?
Just try clearing app data rebooting and reinstalling the app. That problem has happened to me every once in a blue moon and that fixed it for me.

Thanks, I'll try reinstalling the kernel.
Which app are you referring to? because I had this problem no matter which app I used to change the governor (Extweaks, voltage control, setcpu).
Use Jivy's Kernel cleaning script prior to flashing, and try again.

Hi Guys,
My first post here. I am total noob. I rooted and installed the newest ShoStock2 on my at&t galaxy s2. Everything works perfectly. I couldn't be happier. I also went bought the setCPU for overclocking it. That too seem to be working fine.
My question is. I didn't set up any voltage requirements. The only thing I did was to set it to 1600 MHZ and 200 min and change the governor on the bottom to Lulzcrative. Will this work? Do I need to actually do something with the voltage? am I really on 1600 right now? I cannot tell.
I ran a quad test (I now it is meaningless in real world) it came 2818 yesterday. I ran it again this morning ..... It froze and took my battery from 45 to 9 in less than 3 mins!!!!!! The phone got really hot. I took out the battery right of way. The battery life showed 23 percent this time.
I got little afraid of the quadrant testing ... The phone seems to run good without that but I am not sure if it is set up how it is suppose to.
Could someone help me out please? I tried reading the forums and that is where I got the idea in the first place to overclock it.
So to summarize it, I guess phone is fine right now but I am not sure if I set up setcpu out properly.
I am on the newest shostock2. I have galaxy s2 on att. I am pretty good with computers and phones but not sure about voltage and other problems with relating to setCPU.
Thank you advance for helping me out.

Lots of questions there. Phone overclocking is the same and at the same time different than PC overclocking. I too bought SetCPU and due to bugs and problems have completely abandoned it. Honestly with the exception of running an epeen benchmark there is little incentive to overclock. Find a newer Kernel (I use NEAK which has no overclocking ability) and install it, performance is stellar. You really have to ask yourself, is my phone slow enough that I need more CPU power to make it faster?
To see what time your CPU is spending at a given clock speed, download CPUSpyhttps://play.google.com/store/apps/details?id=com.bvalosek.cpuspy&feature=nav_result#?t=W251bGwsMSwyLDNd, you will be surprised to see your phone spend very little time at it's max clockspeed.
Due to the immaturity of the fab process for our CPU's (well SoC), what is a stable overclock for one person might not even load for another. These CPU's are not like an Intel Sandy Bridge, with 1Ghz of free overclocking, nearly guaranteed. You can certainly play with voltages to try and attain a higher overclock, but at the expense of CPU lifetime, as well as battery.
Additionally, it takes a new Kernel 3 or so full charge, discharge cycles on a phone to really 'settle in' and 'learn' a particular phones battery, while yours got hot, which to me indicates an endless loop of some kind running in the background.
My advice would be as follows: Choose a ROM you like, feel free to play with different Kernels, again, I use NEAK, which does not work for some folks, or crashes or whatever. Give it several days to 'settle in' and if your still not happy with performance or have stability problems, try a different governor/scheduler. You really need to establish a good, solid baseline of your phones performance and make small changes and give them long enough to establish any changes to your phones overall stability. Basically running cowboy through your phone and making changes will have a negative overall outcome. Make small, documented changes, test and see what overall effect this has to your phone's stability and battery life, and make another change.

I'm just going off what I've seen in the Siyah/NEAK threads. Most of the lock-ups/random reboots I've heard people having had used the cleaning script. Either that or its just coincidence.
I may be wrong but I think that using the kernel cleaning script actually solved most of the lockups. Perhaps I misunderstood the threads.

Hmm, well I've just manually wiped cache and dalvik and have never had problems between roms/kernels.
Sent from my SGH-I777 using Tapatalk 2
What I'm running:
Latest NEAK kernel + AOKP build 36.
Issue also occurred in Phonebricker + NEAK (sammy version).
My issue:
Occasionally the OS will get extremely slow, like you would expect if the phone were running at 100mhz or something. Everything continues to work, just reeaaallly slow. For instance, music playback gets very electronic-y as sounds are stretched out, tapping one of the capacitive buttons takes 5-10 seconds before vibration/feedback, and another 5-10 seconds before a menu pops up. I managed to get the NEAK configurator open and scrolled to the CPU tab, and it claimed I was at 1200mhz - though the phone didn't even get warm so I'm skeptical.
I'm guessing since I've done a full wipe between phone bricker + NEAK and AOKP + NEAK, the only thing in common are my apps and the NEAK kernel, so it stands to reason it would be one or the other causing this. My wife's GS2 is running AOKP + NEAK as well though and we haven't experienced this problem on it yet (but it's intermittent so it might be there, just hasn't happened yet). I'm currently running conservative governor + SIO, but it has also happened on conservative + NOOP.
While I could just change a bunch of sh!t and hope it goes away, I'm more interested in figuring out what's causing it, and fixing it properly. How can I figure out what's going on? What will log this kind of thing? What do you guys recommend?
Thanks!
this is really easy/simple. flash a different kernel. all devices are not created equally so you need to just try everything that we have and see which best fits your device.
if you had this issue on 2 different roms with the same kernel then you've answered this question in your post for yourself. it wasnt even necessary to post this dude. change kernels. done.
some phone like neak kernel, some phones dont. some phones like siyah, some phones dont. you cant "fix" that unless you get a different phone and try neak again. but even then it my not "fix" this issue because nothing is broken.
Well, what if it's something as simple as the governor I'm using or an undervolt setting? I'll probably flash back to your kernel though, but again it'd be nice if I could figure out exactly what the phone is doing when it's "super-lagging".

If you're undervolting when this issue is happening, change it back to regular voltage.
I can attest to the slow downs and the screen lock ups. I have been using Tasks kernel for the past week and a half. Going back to try NEAK one last time. If it gives the same results I'll have to give up on it. I don't under volt hardly at all by the way. Like maybe -25 per step so it isn't that, and when I first experienced the issue I tried Evey possible io scheduler / governor combo under the sun. All yielded same darn results.

Stock & Siyah. My issue with it wasn't major; it just isn't as polished as GB. The difference is noticeable.
Sent from my Galaxy S2
When mine gets laggy, I usually pull out the battery and put it back after 10 min or so. If you are leaving the phone on more than 2-3 days at a time, that could really hurt the memory and phone performance. The phone usually runs on 300 mb but it will run about 700mb ram after 3 days (even force closing everything).
It is not mentioned so I just wanted to cover all bases
After posting about giving NEAK another try, I did. And within 10 minutes got an extreme lag slow down while typing. Didn't touch any settings kernel side. So I flashed siyah kernel and so far no problems. Sux too. I liked NEAK.

Posted this in NEAK thread but also posting it here:
I just installed the new AOKP, used kernel clean script and installed NEAK 2.0.5x, then went into the NEAK Pro config and changed my governor to Conservative and sched to SIO. Rebooted, opened Scramble with Friends and immediately got superlag.
Turning off the screen and waiting 20-30 seconds fixes it (long enough for the phone to go to sleep), but nothing else short of a reboot will help. I can leave it like that for an hour (if I don't let it sleep) and it'll still be uberslow.
Hello Guys
My Mini Pro(sk17) is rooted and i´m using MESA Kernel(Smartass V2), i´m on stock I.C.S
I noticed that Android System is about 40, 45% on battery drain.
I´ve read a lot of things, added some lines at build.prop, but no sucess... its still about 40. 45% of my battery drain.
I´m already using 2g, screen bright very low.
I remember i checked that before flashing MESA that the android system did not drained battery like this....
Is this normal? Is there anything i can do?
I dont use any task killer, my CPU is set to 134mhz to 896MHZ( so is underclocked!).
Any help?
Thank you

I/O Scheduler has no effect on battery life.
The problem - ICS. In the ROM, there is a bug, after charging via AC(wall charger), phone's Android System uses a lot of battery. Why? It's a bug in the ROM, that we haven't found.
How to fix it? Restart after charging.
And there is already a topic about it. Use Search next time before making new topic.

Try setting your minimum CPU freq to 250MHz. It actually uses way less juice then 134MHz!

I've never experienced bigger batt drain when charged AC as opposed via USB?

Changing kernel, governor and frequencies, now my battery last charge was on sunday night, and still got plenty battery for today.
I use kamarush v2 kernel, and it is the best kernel for me.
I used v3, but it is not as good like v2.
Hope, the kernel will goes to higher level, like in X10mp
Hi,
I have a problem when i use any ICS rom with any version of siyah kernel, my phone always switches off at random times and i have to pull the battery to boot up again.....i usually wake up in the morning to find it off and with most of the battery life drained.
Every time i flash a rom i do the usual clearing the data/cache/dalvik/superwipe and kernel cleaning script and it still shuts down.
I have been using Phenomenal kernel instead and that works perfect and never closes or experience battery drain but i want to use siyah for doing dual boot.
Anybody got any ideas to what the problem may be?
Cheers.

Oh, don't set minimal CPU freq below 200 MHz, cause it results with SoD.
It is sounding like that sleep of death but why is it working perfect with the Phenomenal kernel?
I have not done any undervolting i have just been flashing the roms as they come, i will try CPU spy and better battery stats and see what they say.
Cheers.

If you've found one that doesn't cause the sod, use it. Its all about trial and error

Hello
I'm using the Ultima rom and I need help undervolting. In Stweaks there are only sliders per frequency but on stock with Siyah kernel, there was a drop down list with -25 and -50 on it.
I don't know how to edit using the sliders. How can I get the drop down list back?

check for boeffla kernel it has drop down list but make sure it works for ur Rom or ull screw it up
No offense but if you can't figure out a slider, perhaps you shouldn't be undervolting.
Besides, most devs don't believe it saves battery anyway. After stopping undervolting recently myself, I'm inclined to agree

Nah, I finally learned how to do it using System Tuner. I was confused because when I moved the slider a bit, all the numbers changed and I couldn't figure out where the -25 was gonna be at. But I got it now.
Are you sure it doesn't attribute to battery life? I went a whole -100mV in general and for me it seems to have improved a bit. Not by much but it is noticeable.
Anything else you recommend? I'm completely new to the device, but I familiarize with tweaking very quickly.

I've been undervolting for about 3 years but I have noticed no effects by ceasing this activity. I have noticed improved stability though. I actually notice more effects by tweaking things like CPU sample times etc
I use SetCPU

You mean better stability after or during the undervolting? And what's your stand on OC? Do you also think UC saves battery as well?
Lol sorry, I just like asking people that know about these things before I try messing with them.
Yeah its more stable at stock voltages.
I recently stopped overclocking. I don't have any particular reason not to overclock. I was troubleshooting an issue and overclocking and undervolting should be the first to go when doing this. Just didn't have a need to re-overclock.
One thing I would say though... if you're overclocking, don't add more voltage than 1400 MHz is set as stock... that adds heat. Heat + clock = damage

I see. Thank you very much for all this.
But I ran into a problem. Screen flickering. When the screen is off and I press the home button, a bright flash appears then the lock screen turns on. That's the only problem I've been having and it's scaring me like crazy. I've seen some flickering issues but none like this one. Do you think it has to do with the volting? I've restored normal voltages and hasn't happened so far. It's happened twice since last night and today. Both after undervoltage. I hope that was the cause.

No, it doesn't have anything to do with undervolting. It just happened again. I really can't tell what it is.
