I only noticed this recently but it's probably been happening for a while
(doesn't seem to happen on 2.6.26):

ps aux
USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
root         2 83033595  0.0  0     0 ?        S<   10:30 21114574:23 [kthreadd]
root      1740 83078470  0.0  0     0 ?        S<   10:31 21114574:23 [md0_raid1]

Seems to happen only to kernel threads and at random. Last time I booted
it was two XFS threads.

Before I start another bisection, does anybody have any ideas?
