>Release: FreeBSD 2.2-ALPHA i386
>Environment:
AMD 5x86-133, 20 Meg ram, 411 Meg sd0, 2.1 Gig sd1 running
2.2-ALPHA.
>Description:
I mounted devfs on /mnt, then mounted /dev/sd1c on /mnt
(forgot about devfs). Then, when I tried to umount, the
machine did a cold boot (no panic). I was trying to
configure sd1 to eventually be sd0 (finally figured it out).
>How-To-Repeat:
mount_devfs devfs /mnt
mount /dev/sd1c /mnt
umount devfs # message saying devfs wasn't mounted...
umount /mnt # probably not what I _should_ have done, but...
# instant cold boot (no panic).
>Fix:
don't mount two different devices on the same mount point...
