>Description:
Chinon CDS-525 answers to all eight LUN's. And I think it really
shouldn't... Here's a copy of prints I get during boot (I don't
know if the first one about sync requests is of concern):

>How-To-Repeat:
Connect a Chinon CDS-525 to your SCSI adapter and observe. :-)

>Fix:
Add something like the following to /usr/src/sys/scsi/scsiconf.c
to the table scsi_quirk_patterns:

	{T_CDROM, T_REMOV,
	 "CHINON  ", "CD-ROM CDS-525  ", "",     SDEV_NOLUNS},
                                         ^ perhaps V11 here

Please note that I haven't had time to compile a new kernel yet so
I don't know if this really works. But because there are already
two other Chinon's in that table this seems to be quite logical fix.
