SCSI CDROM Problem, cannot mount...

[Feico Dillema <dillema%cs.utwente.nl@localhost>]

Hello,

I recently bought a Media-Vision portable SCSI-2 ReNo CD-ROM, and
tried it on my NetBSD-1.1-Amiga 2000. It failed :-(.

First of all this is one of these SCSI devices that doesn't handle
non-zero LUN queries, but I don't think that is related to the other
problem. At boot-time NetBSD recognizes the CD-player correctly, and
boots ok when the cd-drive is empty (well, I get some error-messages
due to the LUN-problem, but I think I can ignore those for now). With
a CD in the drive NetBSD `hangs' while trying to identify/read the
disk. Only until I remove the cd-disk, NetBSD continues with its
boot-sequence. 

After booting without a cd inserted in the drive, I tried to mount a
cd-disk. This fails. I used (among others):

mount_cd9660 -o rdonly /dev/cd0a ./cdrom
and
mount_cd9660 -r -o rdonly /dev/cd0a ./cdrom

The result is a spinning CD-ROM drive, apparently trying to
read/identify the disk repeatedly without success. The mount command
does not finish and it doesn't give error-messages. I generally have
to reboot in order to try again.

The CD works perfectly under Amiga-Dos (3.1). I haven't tested the
CD-rom at other architectures. I tried to test it under NetBSD-386,
but could not get my hands on the necessary SCSI-cables in order to do
this. I therefore cannot say whether this is NetBSD-Amiga specific or
not. 

Equipment:

A2000 with GVP-Combo 68030
2 SCSI Quantum Harddisks
Media-Vision portable SCSI-2 ReNo CD-ROM
InfoMagic TeX CD-Rom disks, ISO-9660 with Rock Ridge.


Hope you can help me, or help me find and correct the problem.

Feico.
