Entropy, would an increase in force closed be a kernel issue? Since going to 2/28 I've noticed an increase in force closes. For instance, Pandora was whigging out on me so bad yesterday I just uninstalled it. this morning, the web locked the phone up for a minute then force closed.

If this is a Kernel possibility, tell me what you want me to do to troubleshoot it.

So far to troubleshoot it myself, I wiped the phone clean, reverted back to stock, re-rooted, reapplied kernel, reapplied UnNamed

Here's a list of current installed apps (Limited it to try to narrow problems down).

TSF Shell

BBS

Enhanced Email

Harmony Link Remote

WiFi is on 24/7

GPS and BT have been off

Thanks.

It'll also have a git tag after it - I should probably start posting those. :)

Eventually I'll add more identifying information... but I'm trying not to poison my github repo with too much "personal" specific stuff.

is there any way to flash back stock kernel ? without resetting all the settings on the phone?
[AT&T Samsung Galaxy S II SGH-I777] dayv:
Yes, go to here

http://xdaforums.com/showthread.php?t=1286432

Download the package and extract the pda.tar, from the package, then extract the kernel from the pda.tar.

Then flash that kernel via heimdall, or adb, or re-tar just the kernel and flash in the Odin pda slot.
[AT&T Samsung Galaxy S II SGH-I777] dayv:
I've been running 10092011_ exp kernel with a slight uv for two days and all has been good for me.

It has been very stable, no crashes or force closes of any kind.

Battery life has been good with no unusual battery stat reports for me.

No data issues either, data connections (wifi, hspa) have been pretty much the same as stock for me.

All said, I'm very happy with the way my phone has been running with this kernel.
[AT&T Samsung Galaxy S II SGH-I777] ljwnow:
does this new updated kernel support uckj1?
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
No. I have not had time to mess with J1 and figure out the wifi issues, as I've been experimenting with arighi's PM patches and trying to get ramconsole working so that if things ever start crashing, there will be last_kmsg logs to pull. Plus DG hasn't yet released a package without bootloaders.

I'm not a big fan of leaks, after seeing the pain and suffering the Infuse ROM-side guys went through with UCKI3/I4 - the only thing good to come out of those leaks was updated camera libraries.

Newer is not always better.
[AT&T Samsung Galaxy S II SGH-I777] ljwnow:
I hear you. I guess I will just return to stock and wait for your update. Thanks a lot!

Voltages

Does the kernal included in gtgs noname rom come already undervolted ? Reason i ask is when i go to voltages in set cpu while running the noname rom my voltage selections seem to be already undervolted or the included kernal has overvolt also ?
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Everything should be stock. I did notice that in SetCPU also - it may have been a result of the fact that SetCPU is a TiBu restore on my phone, it may have kept the voltages from my Infuse.
[AT&T Samsung Galaxy S II SGH-I777] samsungcaptivates:
Hmm i have never used tibu to restore mine was fresh

---------- Post added at 09:28 PM ---------- Previous post was at 09:18 PM ----------

What should the stock voltages be for specific freq.

heres mine

200 mhz 975 mv

500 mhz 1000 mv

800 mhz 1100 mv

1000 mhz 1200 mv

1200 mhz 1300 mv

1400 mhz 1300 mv

1600 mhz 1450 mv

i noticed that all freq allow up to 1600 mv
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Those are the stock voltages.

The original default voltage settings for a non-OC kernel are at https://github.com/Entropy512/linux_kernel_sgh-i777/blob/master/arch/arm/mach-s5pv310/cpufreq.c#L640

Those are for: 1200, 1000, 800, 500, 200 in that order.

1300mV @ 1400 and 1450@1600 are the defaults from codeworkx's megapatch (which rolls a bunch of netarchy's patches together).
[AT&T Samsung Galaxy S II SGH-I777] samsungcaptivates:
AHHH ok i got it now. i still dont think i want 200 mhz clock with 1600 mv ha ha. can we say heat problems. anyways thanks i just didint know but it must allow for overvolt
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Yes, that was one of the big differences between netarchy's voltage control mechanism used in all GS2 kernels I know of and my Daily Driver on Infuse, and the undervolt mechanism bedwa used in Infusion - the Infusion method was UV-only, netarchy-style gives full voltage control (since some people have to bump it up at the higher clock speeds.)
[AT&T Samsung Galaxy S II SGH-I777] mcorrie1121:
All mine are 25 mv below what you list. Odd.

Any good guides for UV values?
[AT&T Samsung Galaxy S II SGH-I777] tboooe:
Since I am a noob (came from 2.5 years with iphone) I was a little nervous about rooting, restoring, CWM, etc. However, everything updated fine! Looking forward to the next release. Current kernel is working just fine.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
I used to know of one, but I don't remember it now.

I suggest start at -25 across the board, then if that's stable for a day, another -25.

Also download StabilityTest. It'll catch excessive undervolt at high frequencies. Excessive undervolt at low frequencies usually winds up with SoDs.

Once you go past -50 across the board (remember, only try that if you're stable at -25), then start lowering individual frequencies 25 mV at a time - in general you'll be able to get more undervolt at higher frequencies but not always.

Note that once you enter the overclock region, the window of valid voltages gets narrower and narrower. Too high and the CPU overheats and crashes. Too low and it doesn't get enough juice and crashes. On some chips, the space between "too high" and "too low" doesn't exist at some of the higher frequencies - it's simply not possible to run that frequency and achieve stability on that device. It's luck of the draw.

im not sure, but i just flashed the newest dd today and when i reboot the galaxy s boot animation is there again, was it always there? i flashed cognition beta 4 the first day i had the phone and from what i can recall when i used to reboot it would just go directly to android with no boot animations.

[AT&T Samsung Galaxy S II SGH-I777] JmPTaz09:
I like that you've tuned it to be a little snappier out of the box on the recent releases (at least the March ones I tried). I don't have to mess with tuning now and 3/5 is running fast and smooth. Don't see any problems with it yet, nice work. I've undervolted heavily (-75 to -100) but otherwise left settings as you've made them. Running with CobraRom BTW.

[AT&T Samsung Galaxy S II SGH-I777] stalked_r/t:
Has anyone seen a change in battery life with the 3/5 update?
[AT&T Samsung Galaxy S II SGH-I777] xpakage:
Too soon to truthfully know.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Yup, however...

In theory this might be the first update that affects screen-on battery performance.

Mali 3-step control allows the GPU to be downclocked/undervolted more when idle. I've also chosen to break legacy compatibility with Xan's Voltage Control for GPU clock control, with ExTweaks being the only interface supported. (Siyah maintained legacy compatibility by disabling the third step by default - I enabled it by default and made the lowest step much lower than the stock minimum.)

People should be able to undervolt their GPU by 50 mV or more - I made a point of conservative defaults for stability here. (But if stuff crashes when you do anything with graphics, undo the UV!!!)

Also the improved hotplugging logic should improve screen-on performance a little.
[AT&T Samsung Galaxy S II SGH-I777] jazzboyrules:
A quick question:

I am testing out UnOriginal 1.3.6 on your DD-03/04-B kernel.

The touchkeys misbehave randomly.

Few examples:

- At times (not sure if it this has happened only when I have just removed the phone from charger), the Home key stays stuck in 'pressed' state. So when I press the sleep button, screenshots get taken even when I am not pressing the home key (it seems as if the home button is in pressed state internally). I can correct that issue if I press the home key myself just once.

So every time this issue happens (This started happening just recently, either after flashing UnOriginal 1.3.6 or DD-03/04-B), I have to correct it by pressing home button once.

- When the home key is in a stuck state as above, if I press the 'back' key or 'more options' key (the left most one), task manager pops up.

Could these issues be kernel related or ROM related? How can I start diagnosing these? Would dmesg help?
[AT&T Samsung Galaxy S II SGH-I777] shoman94:
I just installed this app to check it out. Seems like this app polls the network to learn and find your location. Do you set for every 15 minutes etc? I would look at that app as suspect for sure.
[AT&T Samsung Galaxy S II SGH-I777] jazzboyrules:
I have set cell/location/wifi/bluetooth polling to never in Llama.

From what I see, Llama doesn't look like the cause of this problem, I have been using it since I got my phone.

Llama simply turns on/off the Wifi depending on screen state. I wouldn't have known that the screen was turning on exactly every 15 minutes if I had not looked at Llama event log (because the battery graph does NOT show the periodic 15 minute screen wakes, weird).

Summary: I am trying to figure out what could cause periodic screen wakes.
[AT&T Samsung Galaxy S II SGH-I777] rav4kar:
This happened to me once (DD-02/28) and long ago on UnNamed v221, screen freeze and pressing sleep button gets screenshots ( and long press on back touch key took this loop off), but many suggested that could be due to 'Screen off CRT anim' and I turned it off in Jkay, there is not certain time this would pop up.One thing is for sure in my case, immediately after this incident I got black screen upon receiving calls.

So I rebooted phone once after turning off 'Screen off CRT anim'.

Edit#1: One that caused this behavior with (DD-02/28) was 'Screen on CRT anim'
[AT&T Samsung Galaxy S II SGH-I777] LiLChris06:
I grabbed ExTweaks and just became lost.

Only thing I did was underclock the GPU 1 notch each step.

Guess I need to read up on that.
[AT&T Samsung Galaxy S II SGH-I777] jazzboyrules:
Thanks! That's helpful, because UnOriginal 1.3.6 DOES have screen off CRT animation.

@shoman94, I never had this issue with SHOstock 1.9.3 Can you please throw some light on the relationship between screen off CRT animation and 'stuck home key' issue (if there is any)?

@Ryude, have you noticed this 'stuck home key' issue or has any of other testers?
[AT&T Samsung Galaxy S II SGH-I777] DefTaker:
Glad to know it isn't just me...I feel the exact same way except at least you were able to do something. I opened up ExTweaks and freaked at the settings so I didn't touch anything and backed out of it. :o

I tried to read up on it thru this thread http://xdaforums.com/showthread.php?p=23252486 but don't understand it still so I haven't touched it.

On a side note, I'm going to have to give it a longer while to sit but 3/4-B seemed to have better battery than 3/5. <-- Again, I may have to let 3/5 marinate a bit longer as this could just be me. I'll repost regarding battery life later tonight.
[AT&T Samsung Galaxy S II SGH-I777] shoman94:
Well.... Funny how it has happened on my wife's phone before and I'm not sure why. I can tell you though that since 1.9.2 I figured out that if CRT on animation is done via services.jar edit then setting the screen off animation in framework is redundant. The bools setting is not required. So that being said my cart off animation via bools has not been enabled since 1.9.2.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
I've never had behavior like that with crt-off... At least not however jkay does it.
[AT&T Samsung Galaxy S II SGH-I777] shoman94:
I'm not sure what was behind it. It was a few releases ago when I was running siyah. Its highly unlikely its a kernel thing IMO.
[AT&T Samsung Galaxy S II SGH-I777] desiromeo719:
Entropy, Ive been reading up a lil on schedulers...and as i read correctly from your first post your kernel seems to still be running BFQ....

From what i have been reading SIO, NOOP, Deadline all seem to be a better bet that BFQ? What are your thoughts?

[EDIT] - Also just headed into ExTweaks and tried to change the scheduler and it seems like your kernel doesnt support sio? Why?

Also from there it seemed the default scheduler was CFQ and not BFQ?
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
BFQ vs CFQ and defaults - that's covered in the changelog for 12/08 and a few pages back.

I haven't done sio because I never saw the need for it and honestly, I sometimes question if I should've put bfq in.

Going to be a small maintenance release tonight - the default GPU voltages are slightly higher than they need to be due to misreading some #ifdefs in the code. Not dangerously so, but not necessary.
[AT&T Samsung Galaxy S II SGH-I777] smknutson:
As far as the "stuck home key", I can confirm I have it as well. I'm still trying to find out what aggravates it, but it is a tad annoying trying to turn the screen off and having it take a screenshot instead.
[AT&T Samsung Galaxy S II SGH-I777] rav4kar:
smknutson, do you have "Screen on CRT animation" on? even I could not track it as well it's very sporadic! I have "Screen off CRT animation" always, got this "stuck home key" on a day I turned on "Screen on CRT animation" and then I turned off only "Screen on CRT animation", since then NO "stuck home key"..so basically I "guessed" it could be "Screen on CRT animation".
[AT&T Samsung Galaxy S II SGH-I777] JmPTaz09:
Yeah, I've been running 800, 800 & 950 with the 3 gpu steps you set with no problems. I think maybe 50 above that would be safe on 99% of devices.

Entropy,

First off I just want to say that I've been using your kernel for the past couple of months and I'm totally loving the incredible stability/battery life. I admire your dedication to this project and the knowledge you continue to bring to this forum. Thank you...

Having said that, I am trying to trouble-shoot a little issue I've been having: if I try to use the Swype dragon dictation while listening to music the audio does not fade out automatically like it used to/is supposed to. I've tried searching for anybody having a similar problem with no luck.

I'm not sure this is a kernel issue, but I've had the problem across several different roms. Right now I'm on SHOstock 1.9.4, but it is also happening on ICscrewd.

I'm currently on DD_03052012.

If you can offer any guidance if you think this is pertaining to a kernel issue I'd greatly appreciate it.

Thanks.

Hi, Entropy I had crash to LPM again while charging this time on 3/5/12 on fresh installed ShishirROM. 2/28/12 so far seems stable (and not only crash wise. My phone seems unresponsive and too many force closes on 3/5 kernel). I will try kernels between those two starting tomorrow.

EDIT: Charge 100%, 2/28 did not crash.
[AT&T Samsung Galaxy S II SGH-I777] Solkamman:
Also curious if anybody knows if a kernel requires the same sort of "settle in" period like a ROM does before you start to see accurate battery performance.

I'm flashing the DD's almost as soon as they hit the shelf and want to know if I should slow it down before I make a true judgment call.

3/5 running great on my phone. I have it running at 1600 no uv what so ever.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
That one really looks like undervolt to me... Either that or the cpuidle patch is just bad news for stability. I'm waiting to see if smknutson gets any good data from the 3/5 debug kernel on his SoDs, or if 1/24 is more stable for him.

No settling in required, however it really takes a few days to get a good idea of battery performance. Battery drain can vary a lot from day to day depending on lots of things - for example when some drama erupted on Google Plus a few weeks ago, the constant comment email notifications drove my drain at my desk through the roof.
