Oops on sleep w/2.6.4 tipb 1ghz

[David Bryson]

Got an oops on sleep, this is entirely repeatable.  This is me writing
down the oops then typing it in, so there might be some discrepancies ;-)

hdc: start_power_step (step:0)
hdc: completing PM request, suspend
hda: start_power_step (step:0)
hda: start_power_step (step:1)
hda: complete_power_step (step:1, stat:50, err:0)
hda: completing PM request, suspend

looks like the oops is somewhere in the bowels of devfs... any hints
on what might have bothered the kernel ?
