I think the Lightning has problems with tagged queueing.  If you
send too many commands to it, it generates QUEUE FULL responses
to the initiator.

I'd suggest using sd0 to terminate the bus, as you're more
likely to get active termination, rather than passive from
your CD-ROM.

You can always disable tagged queueing for the ahc driver if you
continue to have problems.
