I see much the same thing under (extremely) heavy disk load, both on
onboard piix4 ide, and on an onboard aic7??? scsi.

Things it isn't:
hardware - too many people are seeing the same thing for that
driver specific - it happens on both ide and scsi, and with both sb and
ess cards
anything blindingly obvious

Currently I suspect something evil either in sound_core.c or sound_timer.c
or (more likely) something scheduler related, but this is wild guessing. Any
ideas?
