I just reproduced this on a system running 4.0-CURRENT from about
Sun Jun 27 01:12:42 PDT
I got a ton of these errors in dmesg and /var/log/messages:
Jun 29 00:17:53 marx /kernel: fd0c: hard error writing fsbn 19 (ST0 40<abnrml> ST1
2<write_protect> ST2 0 cyl 0 hd 1 sec 2)
And it let me try several umount commands and even a umount -f. None
of them actualy umounted the floppy drive and it completly reboot my computer
after about 2 or 3 mins. No panic or anything. Once second I'm looking at X,
next second I'm looking at my BIOS bootup screen.
