I recently installed the Yamaha CD-writer CRW4260T. When booting, the
kernel shows the following error (system message):

----- cut here -----
ahsc0 at mainbus0
scsibus0 at ahsc0: 8 targets
probe(ahsc0:1:0):  Check Condition on opcode 0x0
    SENSE KEY:  Aborted Command
     ASC/ASCQ:  Message Error
----- cut here -----

Even later on when trying to mount manually, I get the same output.

----- cut here -----
# mount_cd9660 -o ro /dev/sd0a /mnt/crw0
cd0(ahsc0:1:0):  Check Condition on opcode 0x28
    SENSE KEY:  Illegal Request
     ASC/ASCQ:  Logical Block Address Out of Range
----- cut here -----

What is wrong here?
