FWIW guys, running a Texstar built 2.6.38.8-pae-bfs kernel here, but my dvd
writer, which works, is (from messages at last boot)
scsi 4:0:0:0: CD-ROM ATAPI iHAS324 A BL1D PQ: 0 ANSI: 5

Assigned to /dev/sr0.

And I cannot duplicate this. My problems are shutdown/reboot related, it
"turning off swap"
"-f" on the next line, and it is hung till I tap the hardware reset button.

In your case I'd suspect something in the Plextor that could be as simple
as a dusty led/ir combo that detects the disk. But dvd writers have become
so cheap they are hardly worth pulling the covers off to check.

Cheers, gene
