@hc:

nevermind, I just tried this 2.6.35.11 kernel and found out it has the same dual core problem. Obviously samsung fixed this somehow in current stock kernels (KG2/KG3).

What do you mean for dual core problem?

Nice to see you here :)
there is a dual core issue in the kernel source you are using. some apps (games) crash or freeze with this kernel version. the issue is fixes with samsung kernel KG2. .

I think the issue is not fixed in KG2 kernel. I have some crashes and freezes with it too..

Workaround: Turn Off sound in such games/apss -> then it runs without any freezes

The problem was very frequent on KE4/7 for me. On KFx it got better but was not gone, since KGx I cannot reproduce it any longer. I have no idea if it is really a sound issue. It feels like a code deadlock, since CPU is getting very hot sometimes it happens...

EDIT: I cannot confirm that this is a sound issue. Even with sound off the problem can be produced.

With sound off in options in game (not with volume down button) problem can be reproduced??

The only way I found to prevent the problem is using a stock kernel > KG1. If you flash CF-Root KG3 to name an example my problem is gone. CF is a pure stock kernel with several script addons.

Been using this kernel for two days. Battery seems similar to stock kernel but i don't like the fact that logcat and dmesg is disabled and lastly that things like android os are hidden in battery stats. I do like to know what's going on in the background on my phone.....

Aww man.. I tried flashing to speedmod k1-t8 but was unsuccessful.

I had flashed kernel under cwm from KF1 to KG3. This part was successful.

Thereafter, opened up Odin, click speedmod under PDA with phone connected by it showed unsuccessful.. anyone know what I missed?
