freshly booted system with X running at niceness 0 no other processes consume cpu cycles.
it is reproducable by creating any kind of output which reads from disk... so i.e. a find ./ in my home directory takes sometimes like 30 minutes on 2.6 (100%cpu load) and sometimes 5 minutes (on 2.4 always 5 minutes ~40%load).
dmesg is another candidate... just doing cat <file> seems not to trigger that problem.
As Willy Tarreau also oberves this very same weirdness - I now know the problem is there and it is not specific to my setup.
