This is question on policy.

The msdosfs will panic and the system will die if you mount a 
floppy with a corrupt format. I have an image of such a floppy
and I can crash my system every time.

The error message is:

panic: isa_dmacheck: no physical page present
syncing disks... panic: msdosfs_lock: locking against myself
...and the system reboots. 

I am using 2.2.7R and have tested it on three separate systems.

The man page for mount effectively says "live with it".

So is this a bug or a feature?
