I was getting similar sense messages on all SCSI devices until I realised
the 1540's BIOS wasn't enabled.  I haven't had a chance to look at the
as driver yet, but I think it's possible it's relying on part of the
board being initialised by the BIOS on boot.

Your disk is apparently behaving, so this might not be your problem, but
what the hell...
