Hi I'm installed the entire package to test, and sometimes the device halts without notice when it is at locked mode, 1x each 15 minutes (and burns battery, using a lot)
If I set no frills to 320-600, conservative, It occurs 1x each 2 hours, but it happens anyways.
I'm installed only the kernel + system.rfs from samsung + wifi updated drivers from arkas, the same.
Fruit Ninja is lagging a lot (on Samsung original it lags sometimes).
Android Music Player + AAC+ Music is lagging a lot.
PowerAMp + AAC+ Music is impossible. Even at maximum speed 744.
Perhaps you have another kernel compilations to test? You can send to me if you wanna.
