More generally, whenever one partition cannot be unmounted, all of the other
partitions should be unmounted anyway. I used to have a problem with an
unreliable disk and/or scsi controller that would force me to fsck every
partition on every disk just because trying to shut down one partition got
stuck. This was the old buslogic driver, not the new one, but I think the
problem is not specific to a single scsi driver.
