Had the same problem yesterday.
I think it is hardware (SCSI controller) related.
I tried two different sets of CDROMs and internal SCSI cables ... no luck.
external CDROM: did not get recognized by "show device".
I tried also to boot the RZ26 (with tru64?) contained in this machine but
it failed also with SCSI error messages.
I had another dead DEC3000/400 (malfunction in L2 cache) sitting around,
so I decided to disassemble the whole machine.
I changed the base board (this is where the turbochannel adaptors as
well as the two NCR SCSI chips and all backside connectors reside).
Then it worked. NetBSD is up and running.
But maybe only reassembling the machine would help, maybe there is a
contact problem between mainboard and baseboard? Of course with
appropriate caution and antistatic wrist strap ...
