Hi Daniel,

thanks for the git branch. Strange thing is with the patched kernel the cpu load goes up after working with my desktop with no obvious reason. top shows a high user and system load but no process using up all the cpu cores. The cpufreq-daemon clocks the cpu cores down to the minimal frequency (800mhz) when idle while top still shows full cpu load but no process using up the cpu. The cpu load drops to normal after I kill X and immediately goes up again if I restart X.

I'm kinda lost here :( Any Ideas?
