2.6.14-rc1: oops

[bytewise@gmx.net]

(Please cc me)

I'm experiencing kernel oopses on 2.6.14-rc1. I'm not able to notice any pattern
in when exactly they occur.

The last one happened when I tried to access my cdrom (managed by automounter).
It didn't work, so I tried to rmmod all the relevant modules.

This kernel is suspend2-patched and compiled with some debugging options.

Please ask if any other information could be helpful or interesting.
