No, without seti everythin seems to be fine except that I cannot watch two 
movies at the same time which is no problem with the old scheduler. I already 
switched back from ULE to the old because at the moment ULE makes working 
exhausting.
I also could play quake(2) and have something compiling in the background but 
I see every new object file in form of a picture freeze. Also every other 
disk access seems to block the whole machine for a moment.
I'll try again if somebody has an idea what's wrong. Then I can try running 
seti wtih nice 20 but that's not really a solution. It's working perfectly 
with nice 15 and the old scheduler.
