Previous kernel 2.6.11-1.1369_FC4 works without crashing. It does however print
the following messages when mounting:

hdb: command error: status=0x51 { DriveReady SeekComplete Error }
hdb: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 }

  I verified that this happens when attempting to mount a blank DVD, but not
when mounting an already written data DVD.  It also happens for me when trying
to mount a video DVD.  I reported this in bug #162295.
