Looks like another that needs adding to the whitelist.
Can you do the test as described in the post I just made to the bug ?

Multi-lun devices like these need to get added as they get found to
the whitelist right now.  In the future we'll have to do something
better about these, like having kudzu detect them, and put the
relevant lines in your /etc/modprobe.conf  saving us having to do a
kernel update just to update the whitelist.

We can't just turn on multi-lun probing on all devices, as this
breaks some devices, by locking up the scsi bus when non-existant
lun's are probed.

I've just been through bugzilla and added a load of these devices
to the whitelist (and sent them upstream too).  If you or anyone
else comes across any further devices that don't work without
max_luns tweaking after tomorrows kernel, then please let me know about
them, and I'll make sure they get added.
