I'm trying to get my Texel 3024 CD-ROM to work with 386BSD with the
new scsi drivers.

I can mount CD-ROMs and access the directories and some of the files
(others fail with errno=EINVAL.)  After a while the machine hangs or
crashes.

I don't think the bug is in the filesystem code, as the same behavior
(crashes and hangs) can be be obtained by:

	dd if=/dev/cd0a of=/dev/null

I've read the cd.c source, and see that there is code that is supposed
to work with !512 byte sector devices, but maybe there is something
else missing.

	--jtc
