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

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.
