	I spoke too soon - attempting to burn a DVD-R (which wodim decided
to do at 20X) provoked a return of the livelock messages which stopped
when I killed wodim, however the wodim process did not die (present in ps
and top, but kill claimed it didn't exist after the first kill). The drive
wouldn't stop spinning and the disc was of course a coaster (plenty more
where that came from).

	This really does seem to be badly wrong - cd0 should be at ata6 and
cd1 should be at ata0
