>Description:

The YAMAHA CDR100 doesn't like multiple LUN probing. If you, for example,
wire down your devices like this

device          pass15  at scbus1 target 5
device          cd1     at scbus1 target 5
device          pass16  at scbus1 target 6
device          cd0     at scbus1 target 6

where target 5 is a "YAMAHA CDR100" and target 6 is another cdrom,
the following message appears in dmesg

(cd0:ahc1:0:5:0): Duplicate Wired Device entry!
(cd0:ahc1:0:5:0): Second device will not be wired
(cd0:ahc1:0:5:0): lost device
(cd0:ahc1:0:5:0): removing device entry

and the other cdrom (target 6) becomes cd1.


>How-To-Repeat:

Try the above example
