There seems to be something wrong with cpu idle time accounting at least
on G5. The value as reported in the cpu lines in /proc/stat seems to be
stuck in the interval [100000,210000] for each cpu, jumping back at
random points. Any idea what could be the problem?
Andreas.

It started with 3.2-rc1. Will try to bisect.
