Your cdrom drive doesn't grok LUNs correctly ... it's possible that the 
driver didn't do LUNs before the recent changes.  To fix this, you can 
add those `ID' strings to /sys/scsi/scsiconf.c in the quirks table.  The 
entry would look something like this:

	 "NEC     ", "CD-ROM DRIVE:84 ", "",     SDEV_NOLUNS},

It's worth noting that the following NEC cdrom drives are already in the 
quirk table:

        {T_CDROM, T_REMOV,
         "NEC     ", "CD-ROM DRIVE:55 ", "",     SDEV_NOLUNS},
        {T_CDROM, T_REMOV,
         "NEC     ", "CD-ROM DRIVE:83 ", "",     SDEV_NOLUNS},
        {T_CDROM, T_REMOV,
         "NEC     ", "CD-ROM DRIVE:841", "",     SDEV_NOLUNS},

Apparently, a number of them have this problem :-)  Try that, and, if it 
works, send a bug report with send-pr.
