I have the kernel panic on poweroff bug leading to reboot also. Probably a compilation flag issue, I'll clear it up for the next build (~6 hrs from now or so, moving is fuuuun)
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] decimusmaximus7:
Mine worked at first but after setting the clock speed at 1.83 it constantly crashes about 5 seconds after startup. It crashes before I have the chance to change the clock speed lower. I've tried re-flashing the kernel but I get the same result. Anyone know to re-set the clock speed?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Schwaxdoc:
I have the clock app. This is the kernel, not a ROM. The clock app was unaffected

Flash back the stock kernel with CWM or ODIN. Next time, keep a stock Kernel on the SD or a stable one JIK.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] decimusmaximus7:
Right, I already flashed back the stock kernel and have my phone working again. But it stays in the loop when I try to re-flash this kernel. It seems like somewhere on the phone it has saved my 1.83 settings and is loading them at boot.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Da_G:
Check /system/etc/init.d, kernel executes init scripts here and your clocks are probably saved in a script.

I'm trying to get the recording sound to be good on my phone, cause usually on samsung phones there is 3 recording profiles to use with the microphone, balanced(default), high sensitivity, and, loud environment (which is what I need). Believe it or not these phones can get amazing sound quality recording like at concerts, partys, or anywhere that's loud. The balanced profile tends to give alot of white noise and really staticy. I like to record at shows, or just simple ideas I come up with on guitar quickly and normal recording with this phone just won't cut it.

Thanks again for looking into it! :)

What are the necessary steps to convert this kernel to be compatible with our cm7 alpha build, I probably have the resources necessary to do it if someone could tell me how

How do I prevent future SODs
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] GalaxySkyrocket500:
What is better with this Kernel versus 0.3? Ive had 0 issues with 0.3..
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Presbycusis:
So I cleared the cache and dalvick cache before flashing the .41 kernel in CWM. When it went to reboot it just goes to the AT&T Think Possible screen and stays there and if I tried to turn off the phone it just reboots and does the same thing.

Had my blood run cold for a second but luckily I was able to backup from Nandroid. I am very new to all this; just rooted about a week ago.

By the way, I am running the newer Gingerbread 2.3.6. Should I try to flash the Bonestocketeer rom or Skyrocketeer rom instead with this kernel or should it not matter?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] bacheezy:
Running "rocketeer" for several days, it's been stable for me. I flashed .41 about 2 hours ago then pretty much left it alone. Tried to use device just now & had sod (reset via 10 second power method...sweet BTW) been using phone since, to post w/ no issues. Just a one time thing at this point. As a sidenote I have tried pretty much every rom/mod made available with no problems like others have reported (even alien versions).will post again if it happens more often.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] bacheezy:
Just remembered that I flashed at&t version of .41. I believe 'rocketeer' is Rogers base. I think Da_g said in earlier post that it shouldn't matter which kernal u flash (att or rogers.) But I'm not sure if I missunderstood.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] arkrain7:
How do prevent the sleep of death? It seems that no matter what settings I try in a few hours I have to pull the battery. I am on .41 and the kernel works great for battery life and performance but it keeps causing my phone to hang. Can anyone please advise? I am on stock AT&T... with root... no other mods... and it is not deodexed.

Thank you for this great kernel!
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] bluerap04:
Have you tried the .3 version? I've had 0 issues with it. I got two SoDs with .41 in the few hours I was running it.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] arkrain7:
No... But thanks for the tip! Is the battery life and performance just as good on .3?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] crispy1805:
I get the sleep of death a lot to with .41. Three times in 24 hours. Never got it with .3
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] bluerap04:
I can't say I noticed any difference, but again I wasn't using .41 for very long either :) Rest assured, the performance and battery life on .3 has been great for me.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] venti-americano:
I am running this with Skyrocketeer 2.0 and getting SOD on version .41 as well. I have tried various clock frequencies and it continues to seemingly randomly happen. About 3 times in the last 24 hours.

Switched back to .3, no problems.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] arkrain7:
Yeah... I have been on it for 8 hrs and it has happened 4 times already. Maybe it has to do with the undervolting already preset on the kernel? The only time I have ever had an issue with the sleep of death is when I undervolted too much (but this was on my Captivate and Atrix).
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] bacheezy:
I cleared cache a couple hours ago. No problem since...
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] arkrain7:
I will try that and see if that fixes it... If it happens again I will flash .3 since it seems to be more stable. Thanks y'all!!
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Girn:
Ill try that too. Also getting sod
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Winlockwood:
I love this kernal and everything about it, but I keep running into issues with .4

Especially when I try to use my camera with the flash on, insta kills my phone (That and youtube)

I'll keep trying other things, but I seem to have no sleep of deaths whatsoever with .2 .

Awesome work Da_G! Keep the gravy train flowwiiinnnn
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] tal0s:
SoD on TPC v2, .41 kernel.

Hope I don't get flamed for this but I did not see a link to .3.

Anyone hosting or know where to d/l .3?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] tal0s:
Looking at this, I have noticed one thing about SoD:

I have two skyrockets, both running TPC v2, both have .41 kernel.

One phone is at baseband UCKJ2 and the other at UCKK1, neither phone has been volted or clocked.

The SR on UCKJ2 has been running absolutely trouble free since .41 was released. The other at UCKK1 had .41 installed today and since has SoD every few hours.

Hopefully this helps. Great work on kernel, BTW.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] arkrain7:
Just to update... I have cleared my cache in CWM in an attempt to stop the sleep of death that is happening with .41... I haven't had any issues since. This might be the fix. I have tried several different combinations of governors and schedulers to try and re-create the problem and no sleep of death yet!

I will know more by morning. That should be enough time to see if it happens again.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] saywhat4118:
On .41 I had 3 sleep of deaths when my minimum speed was set to 192 MHz. Then I put it back to stock, 320 MHz or something like that, no sleep of deaths and it has been a couple of hours now. Also I used faux over clock app to change the governor smartassv2. Its running really smooth.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] arkrain7:
Also... I have tried several underclock and overclock combos with no problems yet. I am currently set with:

scheduler-bfq

governor-smartassV2

max-1782

min-384 (for some reason it defaults to this setting even if you set it at 192)

I am using Voltage Control and I have saved this profile as "Steady Rocket"... Lol.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] yoyochuckd:
Sorry if someone already posted this. New to whole undervolting over clocking haven't changed any settings yet just installed kernel. When finished with phone call phone turns off. What causes this?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] arkrain7:
Nevermind... Got excited for nothing. An hour later I picked my phone up only to find that it wouldn't turn on. I am going to flash .3 until this problem is fixed. It lasted a good 5 hrs before it locked up on me again.

I look forward to seeing what the fix is for this.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Da_G:
Took me a fair bit of the early morning to code/test this, excuse the briefness :)

First sysfs interface is done and ready for L2 Voltages. This is based largely off faux123's CPU voltage interface, and functions nearly identically.

Use it like this:

cat /sys/devices/system/cpu/cpufreq/l2_table/l2_levels

310500: 1000000 1100000
432000: 1000000 1100000
486000: 1000000 1100000
540000: 1000000 1100000
594000: 1000000 1100000
648000: 1000000 1100000
702000: 1100000 1100000
756000: 1100000 1100000
810000: 1100000 1100000
864000: 1100000 1100000
918000: 1100000 1100000
972000: 1100000 1100000
1026000: 1100000 1100000
1080000: 1100000 1200000
1134000: 1100000 1200000
1188000: 1200000 1200000
1242000: 1200000 1212500
1404000: 1200000 1212500
1620000: 1250000 1275000
1674000: 1275000 1300000
1728000: 1300000 1312500
1755000: 1312500 1325000
1782000: 1312500 1325000
1836000: 1312500 1325000

First number represents the L2 frequency. 2nd number is VDD_DIG and 3rd number is VDD_MEM

sweeping OV:

echo "+12500" > /sys/devices/system/cpu/cpufreq/l2_table/l2_levels

(this will overvolt all L2 freqs by 12.5mV)

sweeping UV:

echo "-12500" > /sys/devices/system/cpu/cpufreq/l2_table/l2_levels

(same, but undervolt)

setting a specific VDD_DIG and VDD_MEM for a specific L2 frequency:

echo "1782000 1200000 1300000" > /sys/devices/system/cpu/cpufreq/l2_table/l2_levels

(this sets L2 frequency 1782000 to VDD_DIG 1.2v and VDD_MEM 1.3v)

At the moment you can't control which Core frequency maps to which L2 frequency, they are hardcoded as follows:

192000: 432000
384000: 432000
702000: 702000
918000: 918000
1134000: 1134000
1350000: 1242000
1566000: 1404000
1728000: 1728000
1755000: 1755000
1782000: 1755000
1809000: 1755000
1836000: 1755000
1863000: 1755000

Oh yeah, boot animation works now too, thanks to awesome help from romracer :) Place bootanimation.zip (renamed to sanim.zip) at: /system/media/sanim.zip

Coming soon: Mapping L2 freq to Core freq, exposing GPU freqs and volts in sysfs for 2d0/2d1/3d

After all those values are exposed and tweakable I will return the shipped values to stock so the kernel should be fully stable and SoD free for everyone, then you are free to tweak to hearts content via sysfs :0

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Presbycusis:
Ok, tried.41 did not work for me so I installed .3 because it was supposed to be more stable. When I boot up it still gets stuck at "AT&T Think Possible" screen and it even does this if I flash the stock kernel back. I wiped both the dalvik cache and the cache partition (i am guessing cp is the other "cache". I don't see any other options in CWM) before flashing the kernel. Is there a step I am missing here? Everything is back to normal after restoring nandroid backup. Does this kernel just not work with 2.3.6?

Also, will it hurt the phone to keep restoring from backup when I have issues with roms, kernels, etc. or can you pretty much do it an infinite amount of times?

Thanks in advance!
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] the2rrell:
technically you should be able to restore back ups as much as you'd like. but until we get are own CWM i would not go willy nilly unless you want to have to return to stock or flash 3e recovery at some point.

but always remember that Nandroids DO NOT replace kernels. as of right now it does not matter since we are all on GB but once cm7 kernels drop or ics kernels drop. you will have to remember that flashing a gb nandroid on a cm7 kernel or ics kernel will not work. you will have to odin a kernel that fits the nandroid then flash it.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Presbycusis:
So I have to flash the kernel from the program ODIN? I was doing it though CWM. Is that why this .3 is not working for me?

How can I make sure which kernel I have now. I think I flashed the stock kernel back. "About Phone" says Kernel version 2.6.35.11. Is that correct?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] the2rrell:
your good for now bruh.....BOTH stock kernel and Da g's kernel are gb so it makes no difference right now. and the CWM we have is for the T-Mo phone not ours. as far as why you cant get it work. i have not any issues with any of da g's kernels except the SOD thing. but all you have to do is hold the power button for 8-10 sec and it will reboot with having to do a battery pull
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Presbycusis:
I had to pull the battery because every time it rebooted, it would stick on the opening screen. When I flashed back to stock kernel it did the same thing. I did a factory reset before the recovery and it was all good. All of this I did through Clockwork. I don't have the option to clock over 1.5ghz in System Tuner so I think it is still stock. I don't really know enough about it to trouble shoot and don't want to screw anything up since it is working fine now. Also, I want to avoid any trouble when CM7 or ICS comes out. I know I need to flash original .tar to update.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] the2rrell:
dont sike yourself out......lol you can flash away. are you wiping delvik cache after you flash the kernel ??

and im not saying that you arent safe to use the CWM i was just letting you know me and others are noticing that that flashing and backing up and restoring with it have eventually lead to the need to HAVE flash 3e recovery and wipe with that stop the force closings on multiple roms.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] twopumpchump:
Nandroid backups will and do replace kernels. If you want to see just flash Da_G's kernel and then go to cwm/backup and restore/advanced restore and choose restore boot.img from your original stock backup. Then reboot and go to settings and see what it says :)
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] the2rrell:
in the past if i used a nandroid to restore ( not in advanced options ) and just clicked restore the kernel would never get loaded and i would get loops from froyo to gb or cm7 to gb or vise versa i would have to odin the matching kernel to get the nandroid to work.

apologize for wrong info but i would like to know now too......:D
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Girn:
I don't know how to use this sysfs thing. Looks complex :$ I prefer good ol setcpu haha
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Da_G:
SetCPU uses the sysfs interface itself :) Just a GUI for it!

And it isn't all too tough for one of those devs to add support for the new interface so you get a nice GUI.. but I'm not likely to be the one to do it.. I bloody hate java! :)

I am building the GPU sysfs interface now, not too long and I will return all kernel settings to stock, I'll post up an init.d script containing all the stock settings, and you can just adjust it in the script (simple text file) and put on the phone in /system/etc/init.d :)

Oh, I forgot, re: TUN/TAP it is compiled in, should work just fine (VPN support is in the stock kernel, I did not remove it)

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] HumanCaviar:
So, this is my second Skyrocket. The first one worked flawlessly (for the most part) with Da_G's kernels. Ran .1-.3pre on that phone with Bonestocketeer + Rooted Stock. The replacement phone, however, does not function the same. The only difference I could identify between the phones what that the MIPS rating on the new one was slightly higher.

Kernels tried on new phone: .2-.41 (.3 current)

ROMS: RootStock, BoneStock, TCP v2, Quickwiz (current)

OC-ing anything above 1566 causes an instant crash and reboot on antutu (cpu stress tests). Bringing up the voltage 25mv increases stability a bit while OC'ing, but not appreciably so.

Installed .41 on brand new phone this evening after installing Melvins stock ROM. Had 2 SoDs within the first hour and really bad graphics performance in quadrant. Phone was lucky to get more than 20fps and stuttered its way thru most all the graphics test. Final score was 1800.

Used a previous kernal of yours...can't remember which for the life of me but it was incredible. Quadrant scores of 4000+.

Tonight's test was on a new white att version.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] tonyfiore75:
Just to throw in my own experiences... I've tried each one of these kernels as they've become available (pre, official release, etc). Anything that has been released since 0.3 has caused multiple SoDs. 0.3 has definitely been the most stable of all these kernels and I always revert back to it after trying each new release. Oh, and just to be clear, I do not make ANY setting adjustments to the kernels (overclock, undervolt, etc). I flash them and leave them alone. So the SoDs have nothing to do with any tweaks.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] decimusmaximus7:
I've had the same experience, except I always go back to the stock kernel because the battery life on .3 seems worse than the stock or .41. Is your experience different?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] tonyfiore75:
Actually it's been quite some time since I went back to the stock kernel. Maybe I should give that a try because I haven't compared the battery life of the two in a while. Hmmm. The battery life with 0.3 seems decent, though, as far as I can tell. Do you notice a significant difference?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] :
been playing around with several of the kernels...i have the i727r, as I'm in Canada on Rogers....so far....0.4 actually has been most stable. about 1 SoD every 30-50 screen unlocks......0.3, 0.41 and another unlabeled one on December 4th all give SoD every 5-10 screen unlocks with same clock + voltage settings...

good progress so far, definitely enjoying it. at least i can flash a kernel, nothing really for ROMs that have caught my attention yet...maybe i'm picky, after being spoiled on the 9100.....just hoping this phone matures as much as the 9100 in regards to development...lol....

btw, voltage control seems to be working fine for me on clocks and stability....not sure if anyone else can confirm...it seems just as stable as system tuner though....setcpu was really bad for stability...
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] decimusmaximus7:
I get about 20% more at the end of the day with the stock compared to .3, although my differences may be due to my usage. 56% of my battery is taken up by the display, I guess due to the amount of time I read things on my phone.

I'm excited for this kernel but I'm just curious if it has the SoD issue that previous versions had.

edit: So i installed the latest build with the sysfs script and it ran normally until i tried a quadrant, got a restart. not sure where to start debugging the issue. with the .3pre1 i'm stable at 1.78. Also I didn't have any issues with SoD for the short time I was running it.
