This is not a bug w/ FreeBSD, but it was strange enough, that I figured I'd
post it just in case someone else sees it in the future.
I have been having problems with a SCSI DAT drive on a BusLogic 946C, where the
tape would never start streaming, and after a long time would error out with
the following messages:
Beginning backup of partition /
DUMP: Date of this level 0 dump: Tue Nov 14 19:33:13 1995
DUMP: Date of last level 0 dump: the epoch
DUMP: Dumping /dev/rsd0a (/) to /dev/nrst0

dmesg output shows:

Hard drive access and everything else was peachy-keen. I swapped tape drives,
same problem, I loaded older OS's and newer OS's. Used different versions of
dump, all with zero success. Finally I replaced the SCSI card, and vwalla, all
worked well. This doesnt make much sense to me, as HD access was just fine, go
figure.
