Just a small crash ;)

I know I'm stupid and probably didn't follow all the rules, but
searching for my CDROM device, I started mounting from end to other
until I would get a success.. instead I got a fatal error when doing:

% mount /dev/matcd0 /mnt/cdrom

The directory existed already, of course. It just froze and ended up
by booting when I tried to switch to a vty (probably rebooted due to 
a timeout and not because I pressed a few keys).

I have attached my kernel configuration in case you can use it for
anything.

% uname -a
FreeBSD rml.datalab.ericsson.dk 3.0-RELEASE FreeBSD 3.0-RELEASE #3:
Tue Nov 10 20:29:31 CET 1998
robert@rml.datalab.ericsson.dk:/usr/src/sys/compile/NISSE  i386

PS: I will go on a 2 week holiday in a few days (please take that into
account if you want a reply)
