FreeBSD vs. SCSI tape drive

Mon Jan 3 09:56:52 PST 2005
I have a backup server:
OS freeBSD 4.7 P25
SuperMicro X5DP8-G2 mother board
Symbios 875 SCSI controller with 1 Exabyte VXA-1 tape drive on
channel 0
Adaptec 3960D SCSI controller with 2 Seagate ST39173LW disk drives on
Channel 0
with 1 Dell Ultrium 2 tape drive on channel 1
2 3ware raid controllers with 2 mirror sets each
The problem:
About 50% of the time dump crashes writing to the Ultrium tape
drive. See the output of dmesg and /var/log/messages below.
A look at the tape drive's onboard error log shows nothing.
The tape drive diagnostics show no problems.
Can anyone offer a solution/insight/sympathy?
If you need more info please ask.
