At boot time, I get these messages:

In /proc/scsi/scsi is this:

The problem is that rather than seven tape drives, one tape drive (with ID
6) and four CDROM drives are attached.  Here are the messages from Linux
2.1.108:

Instead of an actual AHA-1542, I'm using a Tekram DC-300B.  It ordinarily
works fine.  I haven't made any changes to the kernel besides commenting
out "SMP=1".  I've uploaded the configuration for the kernel to
http://jpj.net/~trevor/linux/config-2.1.109-dennis1.txt.
