>Description:
When running 'mount -t msdos /dev/fd0a /mnt' the kernel result is reboot
without unmount. Well it happens the disk not being inserted, it gave
this (from log):

'Nov 29 12:38:08 skumle /kernel: fd0: Operation timeout
Nov 29 12:38:09 skumle /kernel: fd0c: hard error reading fsbn 0 (No status)'

so I pop in the disk that was not inserted at first. I type
'mount -t msdos /dev/fd0a /mnt' hit enter. Nothing happens
first (no green floppy light on) it seems it is rebooting.
It is rebooting, hrm. Here is some info from /var/log/messages

'Nov 29 12:37:48 skumle login: ROOT LOGIN (root) ON ttyv1'

standard or usual entries in log removed

'Nov 29 12:38:08 skumle /kernel: fd0: Operation timeout
Nov 29 12:38:09 skumle /kernel: fd0c: hard error reading fsbn 0 (No status)
Nov 29 12:39:51 skumle /kernel: Copyright (c) 1992-1998 FreeBSD Inc.'

snip
'Nov 29 12:39:52 skumle /kernel: WARNING: / was not properly dismounted'
>How-To-Repeat:
1. Process:
cron,sh,sh,init,csh,csh,csh,csh,csh,adjkerntz,getty,getty,rc5des.

2. See Full Description. I type more .history - nothing there
seem to differ from my memory, it does not log any command of 
mount - last entry: su (this might be just before running mount)

3. It rebooted seconds after typing "mount -t msdos /dev/fd0a
/mnt" and then pressing enter. I could not see anything on screen
after typing the mount command and pressing enter (again - now
with disk inserted) - I am not sure I can repeat the problem like
I write..
