Hi.
After upgrading to 8.1 from 8.0, I recently tried to access the cdrom, by
inserting a cd and going to /mnt/cdrom. This caused ls to segv and the
following message was in /var/log/messages:

The entire /mnt directory is not visible.
I do have a usb printer attached.
Any idea what's wrong? Is this a known problem, or should I report it as a
kernel bug? If so, to whom?
