These are all various kinds of reports of the disk not reporting back
by the time the system expected it to do so.  The usual first culprit
to check is the drive cable.  I've been getting the command timeouts
on -STABLE for the last few weeks, and I'm figuring that the drive is
probably on its way out -- but that it might take months to get there.
