Since when do you have those issues? It's probably a bug in the kernel
(package linux 3.0.2 and 3.0.3).

I just wanted to try what was explained in this thread and must realize
that my DVD writer isn't detected anymore, no /dev/sr0 anymore. And my
drive is hard locked, means I can't open the tray anymore with the
drive's eject button. And the eject command doesn't work either, of
course.

Here's my bug report:
