I've actually seen this problem before when I had two certain CD-ROM's
on the same bus. When I had only one connected I never had a problem,
but I'd be getting these time-out's when I had both. Eventually I
chucked one and the time-out's stopped. The moral of the story is
that you might want to check the hardware that you have connected on
the bus.
