I have a Conner CTD-8000 SCSI-2 Tape drive on a adaptec 2940W PCI
SCSI contoller.  Recently, I wanted to repartition everything, so I backed
everything up via dump.

Aug 26 22:45:06 playpen /kernel: ahc0: target 6 synchronous at 5.0MB/s, offset = 0xf
Aug 26 22:45:06 playpen /kernel: (ahc0:6:0): "ARCHIVE Python 28388-XXX 5.28" type 1 removable SCSI 2
Aug 26 22:45:06 playpen /kernel: st0(ahc0:6:0): Sequential-Access density code 0x13, 512-byte blocks, write-enabled


After repartioning, I proceeded to restore.  All of my partitions restored
correctly, except for /usr.  When I tried to restore /usr, it goes for a while
and then when it gets to some file in /usr/share/man, I get the following
error:

Aug 26 22:37:35 playpen /kernel: st0(ahc0:6:0): HARDWARE FAILURE info:8000 asc:44,80 
Aug 26 22:37:38 playpen /kernel: st0(ahc0:6:0): HARDWARE FAILURE info:f000 asc:44,80 
Aug 26 22:37:38 playpen last message repeated 13 times


At this point, the light on my tape drive is blinking, and I can't even
eject the tape (perhaps it is still "mounted"??).  It seems to me that there
is a media failure here, but why would this cause a hardware failure??
