It's not a bug in udev. It sounds like a bug in the DVD drive's
firmware which should be worked around in the kernel (somehow).
Please send the output of the command:
time /lib/udev/ata_id --export /dev/sr0
(under the Linux 3.2 kernel).
Can you also try the kernel parameter:
libata.force=noncq
or have you tried that?
