wd0s1 = Win95 FAT partition
wd2s1 = FreeBSD partition

>Description:

Attempting to mount a FAT filesystem using the regular mount command, and
then immediately after mounting the same filesystem with mount_msdos, results
in FreeBSD locking up, dumping core, and rebooting.  I have a savecore file
here, but I have no idea how to analyze it - if someone wants a copy I can
gzip it and email and/or make it available for FTP.

It's possible this could be specific to my system - I don't have another
FreeBSD system with FAT partitions to test with.

>How-To-Repeat:

mount /dev/wd0s1 /mnt
mount_msdos /dev/wd0s1 /mnt
wait while system dumps core and reboots

>Fix:
	
Wish I knew.
