scsi0: No active SCB for reconnecting target 2, channel A - Issuing

When I boot the BIOS tells me the following:
Adaptec AIC-7850 BIOS v1.11.01
SCSI #2 - Exabyte EXB-2501
BIOS disabled!
I believe the BIOS gets disabled because there are no SCSI hard-drives
(the BIOS *is* enabled in the Adaptec configuration screens).
I believe someone mentioned a while ago that 2.0.25 had some Adaptec
stuff broken. If so - if there a fix? I'm going to go back through
the 19..25 patches and see what Adaptec things changed and try to get
it back to the state it was in 2.0.18 but it would be nice if there
was just a current patch I could apply to fix the problem!
Thanks for any help. At the end of this email are various messages
gleaned from the /var/log/messages file.
