Summary: Kernel panics when mounting a floppy filesystem
Keywords: BUG VM KERNEL MOUNT
I ran over a bug in 386bsd (with pk 2.4) that I don't have time to hunt
down, but wanted to post here, so that others who've enough time or are
familiar with the code can fix.
The problem occurs when you try to mount a dos floppy with
mount -t pcfs /dev/fd0a /mnt
without a floppy being in the drive. This operation aborts with an i/o
error message, just as one would expect that.
But if you then insert a dos floppy and repeat the command, the kernel
panics with the following message:
kernel panic: trap 12
vm_fault(fe34c400,53e58000,1,0) -> 1
