A guess:

The tape drive did not get auto-config'd in on your last reboot; it was
probably disconnected from the bus or something when the machine came up,
and so the probes never found it.  You should be able to verify this by
comparing your console listing for this boot with a listing for a boot
where the tape drive was indeed found.  Reconnect the drive and reboot,
and everything should be fine.
