Description david 2001-10-01 03:20:01 UTC 
Ok, I know this was dumb to do, but after I mounted a valid floppy (msdosfs), 
removed it, put in a brand new floppy (wihtout umount'ing), and did ls,
the machine locked up completely

How-To-Repeat: 1.) Insert a dos/windows floppy.
2.) mount_msdosfs /dev/fd0 /mnt/floppy
3.) cd /mnt/floppy
4.) ls (it works)
5.) remove floppy
6.) insert a brand new floppy, right out of the package
7.) ls

it locks up.

it is widely known that you cannot change mounted media till it is 
unmounted, since we cannot lock floppy disks like apple did with their 
early hardare, you can physically change them but not operating system 
wise. This is a: Dont do that type of thing. Closingthe PR
