This just happened here again. Or at least I finally noticed that
the fan on my notebook seemed to be running hard for much longer
than usual. :)
Powertop showed 2.6.24-final running with 10000-36000 wakeups/sec,
with *nothing* significant running: top showed 97+% idle on both
cores.

this shows you're having various types of really bad things going on, like PCI
master aborts and the like. Those would certainly be a factor in waking the cpu
up;
they're basically hardware exceptions, and I can totally believe (would need to
find out
from hw guys how this works in practice) that this sort of serious error would
keep the
cpu out of deep C states until resolved.
..
Or perhaps some initialization on the main-boot patch
just doesn't happen on the resume-from-hibernate paths ?
(either in the BIOS or kernel or drivers ..)
