First of all, thanks for the quick response.

Anyway... I recompiled the kernel (2.6.22.2 now) with pure libata, CONFIG_HZ to 1000 (instead of 250). No effect yet.

Well the system is low on memory (312M) but that was the last thing i would've been looking for since it somehow got the win32 gui and some games to render and work properly on it.

When am I supposed to check this? During idle it's like the following: state count: 8 active state: T0 states: *T0: 00% T1: 12% T2: 25% T3: 37% T4: 50% T5: 62% T6: 75% T7: 87%
Any additional comments on this? :) Thanks a lot.
