And here we are. I really don't know what to try/log/debug or show for
someone who might be able to fix this (or at least find the reason to
why it doesn't work).

What I did now (after a few days uptime with several suspend to
ram/resume cycles) is that I inserted an audio CD into the drive.
Normally the disc will mount and gnome will ask me what to do. Now
nothing happens. So I tried to mount i manually using "sudo
mount /dev/sr0 /mnt" (my laptop runs Ubuntu 8.04).

mount tells me that I need to provide filesystem (-t) and dmesg now
contains

I'd be happy to file a bug report (and provide more info) but I just
don't know where to turn.

Thanks in advance,
