That seems to be the case with CM7 on SGS. Could be a bug in 2.3.4?
[Galaxy S II Original Android Development] xtrememorph:
Have you try wipe cache and wipe dalvik-cache?

If those doesn't work, full system reset?
[Galaxy S II Original Android Development] xtrememorph:
So far on Lite'ning ROM v2.1 (from Lite'ning ROM v1.5 + Kenerl 7, no cache/dalvik-chace wipe)+ kernel 8

no WiFi issue

yes auto reboot issue (once so far during 12 hour usage)

no auto start while on charge issue

yes email not sync fixed by clear app memory

Dear Tegrak, are you working on kf1 kernel? Any ETA? thanks
[Galaxy S II Original Android Development] tegrak:
There are too many kernels @.@ I'm confusing..

all kernels are for whole Euro models?
[Galaxy S II Original Android Development] lukemo:
I think that kf1 is out for whole Europe and Asia...but first impressions on kf1 rom upgrade are very good...so we need an upgrade of your kernel...thanks
[Galaxy S II Original Android Development] tegrak:
Thank you to explain this. I'm going to download KF1. :)
[Galaxy S II Original Android Development] tegrak:
kernel based on KF1 is available. :)

Is it possible to flash an theme that is zipped via this recovery menu ???
[Galaxy S II Original Android Development] lukemo:
Thanks a lot Tegrak for your support.

I'm trying it with Angelom XWKF1 1.0 and it seems ok, with benchmarks more or less 5% superior than ke8 chainfire with the same ROM
[Galaxy S II Original Android Development] redbullman:
To clarify, if I want Tegrak's KF1 kernel, I install the stock kf1 rom (already done that) and then flash kf1 tegrak via Odin? As the lag fix is only for Galaxy S, does that mean the Tegrak kernel app in the market doesn't work for Galaxy S2, or is there any benefit in installing it?

Thanks
[Galaxy S II Original Android Development] KLoNe1:
Tegrak-Kernel-Build-23-for-I9100-XWKE7.tar does not work with AngelRom 1.4 (KE7).
[Galaxy S II Original Android Development] redbullman:
Ok ignore my post. Installed the kernel app from market and it works fine.

However I though with this Tegrak kernel you could install cwm zips. Is this not correct? I just tried to install battery mod, crt and green systemui zip and it states invalid package. What am I doing wrong?

Thanks
[Galaxy S II Original Android Development] tegrak:
You can install zip in the Tegrak recovery mode. See op carefully.

This kernel does not support cwm.
[Galaxy S II Original Android Development] aaronsoup:
I'm really confused here - running Litening Rom v1.4. So I have to flash back to stock, then install the kernel - after that, if i flash to Litening again, i'll lose the kernel right? Does that mean this kernel is incompatible with custom roms?
[Galaxy S II Original Android Development] monkley:

[Galaxy S II Original Android Development] hkfriends:
hello there

one stupid question, how can I restore back to stock kernal? (just re-flash by stock kernal by Odin Tool?)

I noticed that all file system changed to EXT4, I worry the stock will not able to use it.... or failed to boot :(
[Galaxy S II Original Android Development] Tricky103:
SGS2 is EXT4. You can flash a stock kernel.. This kernel only differs from stock as it has the ability to flash zips or replace folders etc + custom boot anim..
[Galaxy S II Original Android Development] Tricky103:
Hi tegrak

I used a boot animation renamed sanim.zip, but the boot animation never left the screen.. It just stayed there.. the phone thought it had passed that stage..

This also happens on the JVP kernel with a similar animation to this,

http://niekske.myftp.biz:81/elfinde...2662d&target=930019da56c1e4fc459526382c251ef3

^ is the animation.. It is the rom kitchen stock one. I am testing kitchen builds atm..
[Galaxy S II Original Android Development] tegrak:
Tricky! I am really happy with your special ROM :D :D

And I've just pushed romkitchen boot animation, it works perfectly on my phone (SHW-M250S)

Hm.. what's the problem..
[Galaxy S II Original Android Development] Tricky103:
Not sure.. It works. Just doesnt stop :)

The phone doesnt boot. Just keeps saying rom kitchen
[Galaxy S II Original Android Development] tegrak:
Yes yes. I know the symptom what you said.

boot animation service must be killed by "Zygote" service..

you modified /system folder?
[Galaxy S II Original Android Development] SpoOokY1983:
I'm running on Cognition S2 1.11 and Lulz Kernel is a desaster on my SGSII. It constantly reboots, locks up and is very laggy. I changed to CF-Root KG1 and everything is perfectly. Besides that I can now go to much lower voltages in Tegrak Tool. Perhaps I'll try new releases but currently CF-Root works flawless.
[Galaxy S II Original Android Development] c010:
1. you OC/UV? if yes what's the value you set?

2. which governor you are currently running? ondemand or interactive or etc?

3. which rom you are running now?
[Galaxy S II Original Android Development] tegrak:
* THANKS *

It seems that we have to wait the new kernel source (used for 2.3.4)

something is wrong with 2.3.4 system.

I am still using 2.3.3 and haven't got any problems.

Tegrak Kernel might be working with no error.

Please use Lulz Kernel Build 6~8 on 2.3.3

WIFI issue is confirmed, that is not a kernel problem.

someone wrote how to fix it in this thread.
[Galaxy S II Original Android Development] Kur0saki:
Hi,

Iam on Litening rom 2.0 using lulz kernel build 8.

I have had no reboot only one freeze.

I had my S2 on charging allnight noe freeze or reboot.

But i have freezes while charging if my wifi stands on.

I have set the wifi on to turn off when screen turns off, but i have to test it when i come home. Other than that my s2 is stable.

Edit: Had one random reboot now:-(
[Galaxy S II Original Android Development] koven:
Phone restarts during charging, I can live with that for now.

But the reboot while phone off and charging was present earlier
[Galaxy S II Original Android Development] Kur0saki:
With Beta 9 or build 8?
[Galaxy S II Original Android Development] koven:
during charging - 8 and 9

reboot when off - older and 8 & 9
[Galaxy S II Original Android Development] mustafahusain:
Had too many issues with version 9. Random reboots and freezes with or without oc/uv plus no wifi. I am back on CF-Root for now.
[Galaxy S II Original Android Development] tegrak:
I'll upgrade Lulz Kernel only for 2.3.3 KF4 before Samsung releases 2.3.4 kernel source.

For now, I can get 2.3.3 source only and it causes too many problems with 2.3.4 ROM.
[Galaxy S II Original Android Development] programatix:
Weird, I've been using build 8 with 2.3.4 for several days and never experience any of the said problems. The only time the phone reboot is when I disable the data connection using the power (long press) menu. Other than that only the CRT animation got corrupted before the animation starts.
[Galaxy S II Original Android Development] tegrak:
I hope another uses' phone like yours,

but there are many replies about errors since 2.3.4 leaked as you can see :)
[Galaxy S II Original Android Development] koven:
With 2.3.4 and beta 9 I only get reboots while charging. During the day everything works super smooth and battery holds much longer even with my oc settings
[Galaxy S II Original Android Development] tegrak:
Now on BETA

SmartBench2011 (tried several times each gov)

[Galaxy S II Original Android Development] programatix:
Connect PC and charging, no problem. CRT animation corruption gone.

Could it be that the problem encountered are caused by the custom rom used?

Edit: Unable to mount using cifs with error message "out of memory"

Edit #2: Encountered several reboot during usage with Build 9 Beta 2 while using the internet. Actually never have this problem with Build 8. Reverting to Build 8 as cifs is important to me.
[Galaxy S II Original Android Development] koven:
No reboots during nightly charging connected to a pc :)
[Galaxy S II Original Android Development] xtrememorph:
Hi Tegrak, this is from kernel 8.

Lulzactive use almost double the energy than on demand governor.

First decline is when use lulzactive second decline use on demand governor.

Btw, stable since yesterday afternoon no more reboots.
[Galaxy S II Original Android Development] tegrak:
Yes, lulzactive gov scales cpu freqs with real-time work load based on interactive gov.

Surely, it's for performance. and 9-beta2 shows really faster response than ondemand.

BATTERY

performance > interactive >= lulzactive > ondemand > conservative

Faster speed means faster battery out :)

do not use lulzactive who want to make battery life longer.
[Galaxy S II Original Android Development] bullemina:
Many thanks for this great kernel :)

[Galaxy S II Original Android Development] tonysac:
Silly question..I use for a while performance instead of lulzactive, no oc/uv and seems phone is smooth like butter..I know that performance drain battery but oc with lulzactive eats battery too...which one eats more battery? Because if I select lulzactive and oc and then performance with no oc smoothness and speed are the same for me..or am I missing something?

Lite'ning KG1
[Galaxy S II Original Android Development] lowrider_05:
on performance the phone is always even on standby on max freq and thats not good for the battery and the cpu
[Galaxy S II Original Android Development] mach0boi:
LOL. That's how performance governor works. Stay at max all the time. So if u want a better battery don't set yours to performance :)
[Galaxy S II Original Android Development] tonysac:
Thanks for answers guys..lulzactive is the future as it seems to me then lol

I originally was on Build 8 and cifs was working fine. I flashed Build 9 Beta 2 and cifs stop working with CifsManager displaying "mount: out of memory". I flashed back Build 8 and the problem remain.

Any help would be greatly appreciated.
[Galaxy S II Original Android Development] kin0kin:
Question: does the tegrak version includes cifs? I flashed the kernal on my kg1 stock rom, enabled cifs.ko in cifs manager and it is still saying no device found
[Galaxy S II Original Android Development] tonysac:
I returned to build 7..I'm on 2.3.4..everything works fine! I don't have recovery cwm but who cares..!

No lag, smooth, speed, oc everything working again with no problem so far

Lite'ning KG1
[Galaxy S II Original Android Development] tegrak:
hm I remember you said build 7 is very laggy before. but now, what is this? LOL

I think you'll get same problems with Lulz Kernels on 2.3.4 ROM.
[Galaxy S II Original Android Development] tegrak:
I already said this before,

DO NOT USE Lulz Kernel on 2.3.4 ROM

confirmed too many errors. Lulz Kernel is built from 2.3.3 kernel source.

Tegrak Kernel is OK. it's just repacked kernel like CF-root kernel.
[Galaxy S II Original Android Development] frankcilo:
With beta2 and ondemand governor my device reboot:mad:
[Galaxy S II Original Android Development] mynameisjon:
Hey tegrak, running your build 9 with Litening Rom 2.1, and I just realised that I can't see "Time in State" from setcpu anymore. Could see that in build 8, but now it just shows NaN% and no pie chart is drawn.

Yes I realise it's for 2.3.3, just wanted to let you know that the changes from build 8 to build 9 broke that feature of set cpu.
[Galaxy S II Original Android Development] tegrak:
it can be happend with oc app.. try to set frequency again. then you can see.
[Galaxy S II Original Android Development] tonysac:
I thing the errors was with build 8..and of course I know that we shouldn't use those builds for 2.3.4..I took my risk and till now no errors..ill report back later..

Edit

Hmm you are right!.I had some lags with build 7 but nothing special..and of course I was on 2.3.3 then..

Ok but let me try some more on build 7..lol

Lite'ning KG1/Tegrak oc 1500MHz
[Galaxy S II Original Android Development] tegrak:
I should tell you this. see changelog.

build 8 is only cwm added version. not different from build 7.

so again, you'll get same errors. you don't need to report anymore :)
[Galaxy S II Original Android Development] tonysac:
Ok but...that is the reason I try build 7..for no cwm...is it possible the errors on 8 or 9 comes from cwm? That was my thought, but if you say I'm going to have errors then ok I'm going back to classic tegrak's kernel.

[Galaxy S II Original Android Development] nightranger73:
I can't understand your point. Display is the main battery drainer and governors don't affect it. While on lulzactive you've used more display than other governors (the small yellow dots at bottom are screen on time). That's why it seems to drain quicker. Are you trying to cheat us?

The reason you see an almost continuous drain is due to Battery Monitor Widget averaging the readings as it can't read stats constantly but it has to be done at specified intervals

[Galaxy S II Original Android Development] xtrememorph:
I'm not trying to cheat and no comments.
[Galaxy S II Original Android Development] programatix:
Ok, I'm answering my own question.

cifs is working fine with Build 9 Beta 2. The broken one is cifsmanager itself. After uninstalling, restart (this is required), and re-installing, everything is back to normal.

The screen corruption before the CRT animation is still there. It won't appear after a fresh reboot. After using the phone for a while it will start to appear. This has nothing to do with the kernel too as I'm on 2.3.4, so it's my own doing. But since this is the only kernel with cifs support, I'm going to stick with it.

By the way, I noticed that when playing certain games (GPU intense games), the back of the phone gets so hot. I can also feel the heat on the screen. Looking at the battery usage graph, battery usage is more than battery charge, meaning even when charging, the battery level goes down. I do not use any OC. Also data connection and WiFi are off. Is this the default behaviour of the phone (just got it last week)? Or is it my own doing (mixing 2.3.3 kernel with 2.3.4 rom)? Or something is wrong with the game I am playing?
[Galaxy S II Original Android Development] tegrak:
high quality games make the phone stays at the max frequency.

it means phone gets hotter than normal use and consumes more battery.

I think this is just normal.. if u feel wrong, visit near by Samsung service center..
[Galaxy S II Original Android Development] programatix:
Ok, thanks.
[Galaxy S II Original Android Development] xtrememorph:
Can purchase a korean polarbear case for s2 that have a heat sink.
[Galaxy S II Original Android Development] programatix:
By the way, is it possible to have write permission on cifs mounted folder. The account I use to mount the shared folder has full access and I can edit the files in it on my laptop but but on the phone.
[Galaxy S II Original Android Development] xtrememorph:
This post is in respond to Lulz Kernel Build 8 early demise for a great kernel.

What i want to say its, i believe this is a good enough kernel for daily use as I have been using it since the day I got it and have yet change to any other kernel from Lite'ning 2.0 to 2.2.

Today just upgraded to Lite'ning Rom v 2.2 using Build 8 CWM recovery successfully. If without build 8, i would have need to revert to another kernel using ODIN to flash the new update. This I thank you Tegrak effort.

Demise of build 8 is the result of chain of unfortunate events having new ROM and kernel being introduced together at the same time without knowing which could potentially have what issue.

Also, upgrading from 2.3.3 to 2.3.4 without either factory reset, wipe cache or dalvik cache and expected for things to work smoothly is unrealistic. I myself on Galaxy S doing such an upgrade from 2.3.3 to 2.3.4 is a nightmare forcing me return to stock rom for few times, either DocRom, Darky's upgrade or CM7.

Tegrak immediately responded to the issue presuming it was his problem and quickly release Build 9 Beta1, 2 taking the assumption or believe it could have been the new features his implemented on Build 8 was the root cause. This actually reminded me of what happen to supercurio on his last days of building voodoo lag fixed enabled kernels on Galaxy S. He also tried to resolve issue by pushing out several new test kernel immediately to test after a few unstable reports. The result was he left it alone and move on to Voodoo Sound.I hope this doesn't happen to Tegrak.

Tegrak i like Build 8 with CWM and I hope you will keep on working on it. As Lite'ning Rom now upgrade to 2.2 more issues is resolved and we have a stabilized ROM to test, maybe is time we revisit Build 8 and move on from there.
[Galaxy S II Original Android Development] tegrak:
I really want to see official 2.3.4 and kernel source. I'm in hurry but current 2.3.4 issues make me stop to work now.

And also, I'm really enjoying to improve this kernel.

I dunno exactly when, I'll be back on my business and be busier.

before that, you don't need to worry about dev..
[Galaxy S II Original Android Development] docn:
lulzkernel with cifs and cmw recovery for 2.3.4 would be awsome!

[Galaxy S II Original Android Development] xtrememorph:
Lulz build 8 supports it. If you want, PM me but you need to know it could be buggy. However, I'm using it daily and is good.

Is there any plan to develop Lulz Kernel for KG2 ??:D
[Galaxy S II Original Android Development] nightranger73:
KG2 is 2.3.3 so any kernel for 2.3.3 will work as lulz 8 or Tegrak build 25.

The game of matching kernel version with firmware version was born with cf-root kernel since that kernel is made to keep the firmware close to stock as possible (indeed it's a stock kernel with modified initramfs) so that it make sense to flash the same kernel as the one of your firmware just to replace it

KG2 kernel source? or KG1(leaked 2.3.4) kernel source?
