you are right. It looks like CONFIG_4KSTACKS has gone away. I think this was 
introduced in 2.6.12 or 2.6.13 but the SUSE guys have backported a lot of 
current kernel "things".

After several tests I think my problem was caused by the SUSE-default 
IO-sheduler (cfq). Switching to the vanilla default (as) fixed the problem. 
But I think it has something to do with my hardware-setup because we never 
had this problem before!
