During that time, kupdated and kswapd gobble up all available CPU time. The system performs great otherwise, so I've ruled out a hardware problem. It can't be a load problem because during normal operation, the system is more or less bored out of its mind (70-90% idle time). I'm really at the end of my wits here :-( Any help would be greatly appreciated!
