The panic is a bug I fixed already.  The CDRW problem is because the kernel in
the Red Hat Linux 6.0 product does probing of all LUNs by default, which
breaks devices that aren't in the LUN blacklist but can't handle probing of
upper LUNs.  That happens to include your CD-RW drive.  The next product won't
make that mistake....
