Is it possibly kernel related that after loading this update all of my apps that had installed themselves on my internal sd card no longer worked and needed to be reloaded? Or just a glitch in my card? I believe I was on 2-28 before.

Getting freezes playing games, specifically need for speed hot pursuit. 3/5 is Fine, double checked so I know the problem is in 3/7.

Download ExTweaks. Open it. Go to the GPU tab and increase the GPU voltages +50mV

Try the game again.
[AT&T Samsung Galaxy S II SGH-I777] campbellc1052:
I'll try that, can I run extweaks and setcpu at the same time?

I think the first gpu stats entropy saw were correct
[AT&T Samsung Galaxy S II SGH-I777] NJGSII:
I have switched to the test kernel for 3/5 since I was one of the people experiencing SOD issues. If I have another, I'll obviously get you your last kmsg, Entropy.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
That almost surely has nothing to do with the kernel and everything to do with Google Play, which did all sorts of janky ****.

People really need to be better about thinking "was this the ONLY thing that changed on my system? Can I be ABSOLUTELY sure?"

I love how many people have been blaming recent kernel updates for signal loss - when we're in the process of experiencing the largest solar flare/CME hit we've experienced for a few years.
[AT&T Samsung Galaxy S II SGH-I777] DefTaker:
3/05 battery wasn't as good as 3/04_B for me. However, 3/05 felt quicker overall EXCEPT for backing out of an application into the app drawer...the animation would stutter. Other animations were fine.

Switched to the latest & greatest (3/07) this morning and haven't had the stuttering issue on the application back out to app drawer issue that I was having with 3/05. Don't know about battery life yet. I charged the phone this afternoon and will let it sleep and see how it does.

Thank you again for the great kernels and the fixes too!
[AT&T Samsung Galaxy S II SGH-I777] Dimatchka:
Just wondering why the gpu control is not supported in voltage control app with this kennel? It's present with siyah and I was able to under volt far beyond this kernels scope. Just wondering why is that? Overall this is my favorite Kernel thus far! Awesome job! :-D
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Because VC automatically disables its interface when ExTweaks is present - the new 3-step GPU interface is far more flexible and powerful, and VC wasn't compatible with it unless you disabled the 3rd step by default.
[AT&T Samsung Galaxy S II SGH-I777] sirooga:
Thanks for the reply. You are right I didn't think of that.
[AT&T Samsung Galaxy S II SGH-I777] shoman94:
So far I'm not seeing any benefits from having the gpu steps added. If anything I'm seeing more use. Maybe having the steps is creating more load when it needs to change? Idk.... just my experience so far.
[AT&T Samsung Galaxy S II SGH-I777] ryude:
Same here, not seeing any benefits only drawbacks.
[AT&T Samsung Galaxy S II SGH-I777] campbellc1052:
Can I run extweaks and setcpu together
[AT&T Samsung Galaxy S II SGH-I777] ryude:
Yes. /10char
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Apply common sense... If I'm telling people to use SetCPU for stuff AND adding ExTweaks support... Come on, THINK!
[AT&T Samsung Galaxy S II SGH-I777] DeXel55:
Entropy, I got crash again with 3/5 Test kernel; however, last_kmsg is not there after I turned my phone on... I am using root explorer btw but android terminal tells the same.
[AT&T Samsung Galaxy S II SGH-I777] campbellc1052:
I know but I thought extweaks might have been a replacment for setcpu. Sorry
[AT&T Samsung Galaxy S II SGH-I777] :
You know that attitude isnt practiced here. Expecting people to think, pfft...
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Hmm... So the phone completely shut off this time? Weird.

If you're not getting last_kmsg feedback, try 1/24.
[AT&T Samsung Galaxy S II SGH-I777] DeXel55:
It always complete shuts off during charging but only on some of your latest kernels past 12/8 ( big battery charging icon shows up after I press power button, then I take phone of the charger and press the key for 3 seconds and it boots). I though that what crash to LPM meant...

I think it would crash with 1/12 too (it did with 1/02), but it never did with 12/08. 2/28 also seems stable (used it for 2 continuous days) and 3/3 B crashed. I will try 3/3, 3/2 and 1/24 and report on Sunday.

P.S. I have to try stock kernel though for few days to exclude hardware failure. Last time I tried it, my phone never crashed.

I take my words back, I figured out the difference (last_kmsg disappears if phone gets totally off instead of crash to LPM). So this time it turned completely off I suppose.
[AT&T Samsung Galaxy S II SGH-I777] ryude:
Been using 03/07 for the past 2 days, its very smooth and battery life is good as well. I haven't had any sod's either. I don't think its the best, but it is certainly moving in the right direction.
[AT&T Samsung Galaxy S II SGH-I777] NJGSII:
Something interesting just happened. I was on the 3/05 test kernel and as I was in CWM to switch to 3/7, CWM recovery froze as I was selecting options, screen went black and it showed the battery indicator in the middle of the screen for a second or so. Then that went away and the phone re-entered CWM recovery.

It proceeded to do this a second time, time I tried to select an option again.

Hopefully you can find something in the attached last_kmsg.
[AT&T Samsung Galaxy S II SGH-I777] Jank4AU:
Why does it have to be"janky" ****, huh? :-) lol

[AT&T Samsung Galaxy S II SGH-I777] ryude:
Does 03/07 support init.d GPU clock speed and voltage settings?
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
whoops, gotta be careful...

or maybe...

IT'S ALL YOUR FAULT! IT'S ALL YOUR FAULT!!!!!!

http://www.youtube.com/watch?v=YoaJeXDBfIw

It has full support for GPU tuning in ExTweaks, the current profile is applied on boot.
[AT&T Samsung Galaxy S II SGH-I777] ryude:
You didn't answer my question though, can I set gpu control with an init.d script?
[AT&T Samsung Galaxy S II SGH-I777] campbellc1052:
Tried that, still freeZing. Back on 3/5
[AT&T Samsung Galaxy S II SGH-I777] Jank4AU:
That's awesome! LMAO!

15% battery drop with the latest kernel overnight! Not liking that!
[AT&T Samsung Galaxy S II SGH-I777] eep2378:
Might want to give a little more details. That sort of a broad generalization. Any other factors that could have affected battery drop? BBS showing anything funky?
[AT&T Samsung Galaxy S II SGH-I777] Dimatchka:
Compared to 2.18 which drained my battery by only 5 % the latest one increased my Android system use from 9 percent to 19! And also the battery consumption overnight tripled! I don't know what BB is, if it's that battery app then I don't know I haven't purchased it!
[AT&T Samsung Galaxy S II SGH-I777] alacrify:
I'm thinking Entropy shouldn't have to answer this (although he probably will :)). BB is Better Batter Stats - available in the market for free. It will show you what is draining your battery, since it's not likely the kernel. But either way, you need to use that (and CPU Spy is also helpful) to provide information before anyone can help. Or if you don't want to deal with helping figure out the free, helpful, enhancements Entropy provides, go back to 2.18 and be happy. But please don't yell about it.

BTW if you read and research as recommended (and really required if you're rooting and loading kernels) you probably would have picked all of that up already. :)
[AT&T Samsung Galaxy S II SGH-I777] Dimatchka:
Loving the sarcastic :) hahah i thought the app was not free, ill download it and provide better stats this time. btw wasn't yelling, was simply providing feed back. :):)

Anyway, going to leave the phone overnight again with BB running and report back tomorrow on my discoveries. thus far im on battery for 1d 9h with 2.5 hrs of screen time and have 31 % left. Was just very surprised to get -15% in the morning, i cleared the mem and made sure no other apps were running. Anyway, will report back tomorrow.

edit, that app is 2.89 not free :)
[AT&T Samsung Galaxy S II SGH-I777] alacrify:
Actually the smiles are meant to be friendly. Thanks for doing some research to help. And when you use an exclamation point, it comes off as a shout. Apparently a mistake in symbolism all over the place. Real smile here.
[AT&T Samsung Galaxy S II SGH-I777] Jank4AU:
Hey dude, you can get the app on the xda site for free. Although it is very nice if you buy it from the market to help support the developer. :-)
[AT&T Samsung Galaxy S II SGH-I777] Dimatchka:
Thanks for the heads up i was going to post the developers page until i read the "do not redistribute the app without my consent," but yeh i found it ill give it a go tonight. :D

---------- Post added at 11:01 PM ---------- Previous post was at 10:58 PM ----------

Ahhh hahah i see i thought caps was an indication of shouting :p No no i wasnt shouting, Im new still learning and trying to contribute to XDA with my experiences. I was introduced to Entropy through Shomans rom, and this Kernel rocks!!!:) I wont be going back to Siyah kernel anytime soon, so ill keep testing new releases of Entropy!
[AT&T Samsung Galaxy S II SGH-I777] alacrify:
Caps too (real smile again).

And sorry, I thought BBS was free in the market - I bought it because it's that useful when I first started fighting the evil battery drainers.

And yeah, this kernel rocks!!!! (shouting intended!)
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
common sense... If it's tweakable, you can change it with an init script...
[AT&T Samsung Galaxy S II SGH-I777] ryude:
I'm using this to set the GPU settings and it isn't working. I open exTweaks and it shows default values, which I can then set correctly.

echo "Set GPU clocks" | tee -a $LOG_FILE;
echo "100 160 200" > /sys/class/misc/gpu_clock_control/gpu_control

echo "Set GPU Up and Down thresholds" | tee -a $LOG_FILE;
echo "75% 25% 75% 25%" > /sys/class/misc/gpu_clock_control/gpu_control

echo "Set GPU Voltages" | tee -a $LOG_FILE;
echo "800000 850000 900000" > /sys/class/misc/gpu_voltage_control/gpu_control
[AT&T Samsung Galaxy S II SGH-I777] Simba501:
Ex Tweaks resets to default values every time you open it for some reason. I ended up removing it for this reason. I can confirm the commands were correct (observed in other apps), but ex tweaks resets them. That's the cause.

[AT&T Samsung Galaxy S II SGH-I777] DeXel55:
Hi, Entropy. 2/28 does not crash (at least 3 out of 3). 3/5, 3/3 and 3/3B did on first try. I will test 3/2 tomorrow, and then if it does I will return to 2/28 on long run to confirm that it is stable.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
If you change it in ExTweaks, it should remember.

That's why I don't know why someone wants to use init.d for this...
[AT&T Samsung Galaxy S II SGH-I777] ryude:
Because it's just another app I have to install, I don't like having apps sit around and only be useful for 1 minute.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Then why are you complaining about it resetting your init.d values?
[AT&T Samsung Galaxy S II SGH-I777] Simba501:
To force myself to learn/become familiar with the commands.
[AT&T Samsung Galaxy S II SGH-I777] Dimatchka:
I've noticed that my phone trend to skip a little when I'm playing Pandora in the background and I do other tasks such as messaging or open other apps! It would pause then carry on like a skipping track! I'm guessing that's due to the on demand governor!
[AT&T Samsung Galaxy S II SGH-I777] shoman94:
Definitely not. Something else is doing that.

[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Please try the special test version of 3/5 posted a few pages back.

I'm not bothering with a 3/7 variant of it, since you can just drop the GPU voltages by 50 mV in ExTweaks to get the same result.
[AT&T Samsung Galaxy S II SGH-I777] shoman94:
I'm not sure why my friend but 3/2 is better on battery them 3/5 or 3/7.

I was also having issues with the MiLocker app. Upon waking the phone it would show up ass a blank lock screen and I couldn't unlock the phone. At first I thought it was the gpu under volt so I removed that and still had the issue. Ahhhhh well... :D
[AT&T Samsung Galaxy S II SGH-I777] alacrify:
That's been my experience too - I was wondering if we are required to do some ExTweaks to get things back down (i.e. Entropy put it back under our control so put some things back to "stock" levels).
[AT&T Samsung Galaxy S II SGH-I777] :
Nothing seems to beat 2/28 for me, so Im back on it. Amazing battery life, super snappy, no lag ANYWHERE and fast/responsive wakeup.

Im 100% completely happy and satisfied with 2/28. :)
[AT&T Samsung Galaxy S II SGH-I777] shoman94:
The only thing I didn't try was remove extweaks.
[AT&T Samsung Galaxy S II SGH-I777] alacrify:
And I just installed it for the first time today - need to give it a couple of days and see (it's draining faster at the moment, but I'm not counting that as anything yet :))
[AT&T Samsung Galaxy S II SGH-I777] rav4kar:

[AT&T Samsung Galaxy S II SGH-I777] mattdm:
This may be a little off topic, but I'm curious. Entropy, I noticed a few pages back that you use 500-1200mhz as your standard CPU profile. What makes that better than 200-1200mhz?
[AT&T Samsung Galaxy S II SGH-I777] tylercarter:
I would guess less scaling up and down. Not sure though..
[AT&T Samsung Galaxy S II SGH-I777] ryude:
500mhz is only 25mV more voltage than 200mhz, so for him it's not worth the performance penalty to save such a small amount.
[AT&T Samsung Galaxy S II SGH-I777] shoman94:
Power consumption is more then just voltage. Voltage just pushes the power.... mA is more important IMO.
[AT&T Samsung Galaxy S II SGH-I777] rav4kar:
mhz .....mV ........mA...Arrrrghhh!! let's save planet earth! LOL! :D
[AT&T Samsung Galaxy S II SGH-I777] mattdm:
I'm an engineer, so I understand the difference between voltage and amperage, and yes, amperage is far more important. However, I'm not an electrical or computer engineer, so this stuff is all a little hazy to me. I'm just trying to gain a better understanding of what CPU actions and conditions draw the most power and why.
[AT&T Samsung Galaxy S II SGH-I777] ryude:
I've run more than a few full days with 500 min instead of 200, the battery life is damn near the same.
[AT&T Samsung Galaxy S II SGH-I777] alacrify:
Did you notice any difference in quality of use? By which I mean, did you get anything out of it :)
[AT&T Samsung Galaxy S II SGH-I777] AllFlasher:
I run 500-1200. Seems like the small things work better/faster. Going in and out of apps, load times, and my keyboard has no lag which used to happen a lot before changing to 500-1200
[AT&T Samsung Galaxy S II SGH-I777] NJGSII:
After reading these two posts, I'm going to give it a try myself. Will report back with I find.

Thanks guys.
[AT&T Samsung Galaxy S II SGH-I777] ryude:
The transition from idle to load is seamless, by that I mean there is less stuttering when first waking the phone, touching the screen, etc.
[AT&T Samsung Galaxy S II SGH-I777] mattdm:
I've been running it for the last day or so too. My favorite keyboard as far as layout and functionality is Smart Keyboard Pro, but it has always lagged so much that I've been forced to move to Perfect Keyboard. I gave Smart a try again after I switched CPU profiles, and while the lag is decreased, it is definitely still present. Back to Perfect Keyboard I go... :(
[AT&T Samsung Galaxy S II SGH-I777] alacrify:
Me too. Thanks both.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
One less CPU step when scaling. Given that the voltage difference is almost insignificant between 200 and 500, and the fact that cpuidle negates the power penalty from the increased clock rate by shutting off the clock when the system is idle - The power penalty for running at 500 minimum is negligible compared to the fact that the screen is on and consuming power.

It's basically "smartass" but implemented using SetCPU for the screen on/off transitions. This is why I generally resist alternative governors - most of them don't offer anything not already achievable with SetCPU, and the only advantage of having it in-governor (slightly reduced latency during the off-on transition) is not a problem on a fast device like this - It made more sense to have things handled in the kernel on devices that maxed out at 600-800 MHz and had screen-off limits around 200-300.
[AT&T Samsung Galaxy S II SGH-I777] mattdm:
Cool, good to know. Thanks.
[AT&T Samsung Galaxy S II SGH-I777] Dimatchka:
I was wondering, this is non battery related or anything, can you incorporate on your next update the ability to scale the display brightness much lower?

I was told this is mainly kernel related! And to some degree ROM!
[AT&T Samsung Galaxy S II SGH-I777] vladm7:
good idea - my wife's iphone goes much darker than my sgs2 and it's just fine when it's dark.
[AT&T Samsung Galaxy S II SGH-I777] DeXel55:
Entropy, I managed to get last_kmsg with your 3/5 Test kernel after my phone crashed during charging this time. I hope there is something that could help, because I still have that problem. Also I tested 3/2 which crashed, and 2/28 which is also crashed. I will be running 12/8 and samsung stock in next few days to exclude hardware failure unless you find something useful in last_kmsg.
[AT&T Samsung Galaxy S II SGH-I777] :
Everyone should just flash 2/28. Problems solved. :D
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
grrr... damn crash-to-LPM blows away the useful last_kmsg. Really hoping smknutson gets a capture.

As you can see above - 2/28 crashes for some people.

I'm beginning to suspect that there's something wrong with the cpuidle backport... The problem is, though - it's rock solid stable for me, AND has significant measurable benefits...

I'm wondering if these problems are related to the Tab 7 Plus' stability problems - everyone has been blaming it on the closed-source wifi driver, but I'm wondering if that cpuidle code is simply broken.

hmm...

ICS may make this all irrelevant... GIB SOURCE SAMMY!!!!

Either way, main focus right now is:

If experiencing SoDs and crashes, but NOT crash-to-LPM: Try that test kernel

If experiencing crash-to-LPM: Try 1/24
[AT&T Samsung Galaxy S II SGH-I777] :
Are all the people who are getting SoD all undervolting or overclocking? I don't get SoD at all, ever. And your kernels are always rock stable for me (sans that stupid 2/26 weirdo kernel).
[AT&T Samsung Galaxy S II SGH-I777] howtomen:
im with u only kernel that gave me sod was soyah after init.doh.... all other kernels have been fine i like 2/15C tho its a champ
[AT&T Samsung Galaxy S II SGH-I777] jdbeitz:
Ditto.

The only time I've had sod is undervolting too much. Other than that, I've never had and issue with my i777, infuse 4g, and my captivate all running modded kernels. :)
[AT&T Samsung Galaxy S II SGH-I777] jasvncnt1:
Morning all. So if I wanted to test this I just have to install SetCPU and change those 2 values? Never really messed with SetCPU for fear of screwing something up.

Running 2/28 with Turkbey. This ROM seems to have a lot of files in init.d. Do the files in there have any effect on a kernel or viceversa?
[AT&T Samsung Galaxy S II SGH-I777] ryude:
Yes.

Some of the init.d scripts may tweak the kernel, but can be overridden with setcpu or any other app like it.
[AT&T Samsung Galaxy S II SGH-I777] jasvncnt1:
Thanks. Still trying to grasp a lot of this stuff. I havent tried too many ROM's yet but i noticed a lot more files in init.d then pervious. Just wasnt sure what affect any of it has on the kernel. Lots more reading to do.
[AT&T Samsung Galaxy S II SGH-I777] :
If that's the case, then it isn't really fair to have Entropy go running around trying to figure out all these SoD due to undervolting or overclocking. Everyone else (90% of users here) all seem to be enjoying a rock stable kernel.
[AT&T Samsung Galaxy S II SGH-I777] shoman94:
I can't imagine people would report any problems if they are under volted or overclocked.

That's noobish and disrespectful to the dev.... You should be shot!
[AT&T Samsung Galaxy S II SGH-I777] Simba501:
I'm sure they do.
[AT&T Samsung Galaxy S II SGH-I777] alacrify:
Apparently you needed to use the <sarcasm> tag...
[AT&T Samsung Galaxy S II SGH-I777] Alucardis666:
I see nothing wrong with reporting the issues as long as they through up the disclaimer and say they're overclocked/undervolted.
[AT&T Samsung Galaxy S II SGH-I777] alacrify:
Since all chips are not created equal, it throws too many variables into the equation. You need some kind of common hardware denominator to aim at. So before reporting an issue, the UV/OC person should return their phone to that baseline, and report problems from that. Then if they have an issue and want to report that they ALSO had X problem while UV/OC, then it could help others troubleshoot.

But Entropy can't fix hardware variability (well, maybe HE could).
[AT&T Samsung Galaxy S II SGH-I777] shoman94:
Exactly. You can't fix something that is broken because you undervolted or overclocked. O don't care how thorough you are with explaining it because the issue might not occur once you remove the OC and/or UV. The common ground must be stock voltage and clock.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
The following people have, as far as I can tell, had SoD and crash problems even with stock voltages:

smknutson (no feedback recently from him - was 1/24 stable for you?)

tbooe (haven't heard from him recently I think, need to check)

DeXel55 - crash-to-LPM even with stock voltages

2-3 other people have been having issues even with stock default voltages

Anyone who has stability issues with stock voltages should try 1/24 at this point.

I'm wondering if this is related to all of the stability issues the Tab 7 Plus (which is where the cpuidle code came from) has - some people have lots of SoDs with it, others are rock stable. Originally everyone believed it was the wifi driver, but it might be cpuidle instead...

Yeah. If you set the minimum to 500 by default, you probably want to set a screen-off profile with min 200/max 500 or so.
[AT&T Samsung Galaxy S II SGH-I777] :
You may be on to something with the Tab7 cpuidle being the culprit. 1/2 was one of my favorite kernels of yours, probably still in top 3 (2/28 is my favorite followed by 2/15-C).
[AT&T Samsung Galaxy S II SGH-I777] shoman94:
Well I'm running 3/3 currently and while I didn't have any sod's with any.... 3/3 is performing better battery wise then 3/3b. My phone does not like gpu 3step like I mentioned earlier in the week. For me 3/3b thru 3/4b performed about the same.
[AT&T Samsung Galaxy S II SGH-I777] jasvncnt1:
Thanks for a answering. I set a screen off profile (first time using SetCPU) with 200 min. Does it matter what Max is at? Or the priority?
[AT&T Samsung Galaxy S II SGH-I777] posthold:
I was on 3/7 with stock voltages and had one Sod. Was on it about a week before it occurred.
