Mark.
Not seen this behaviour myself. But I also only have one machine with a
dvd-drive in it. And that one has not been updated in several months. (It's
scheduled for a complete rebuild)
Did you try temporarily removing that rules-file to see if it then comes up
properly during a reboot?
Maybe that file is now causing it to disappear?
Are you also certain you have all the necessary drivers included in your kernel
config?
Kind regards
