>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
