second "mount" hangs

[Michael Rothwell]

Hi,

I mounted a JFFS2 filesystem stored on a 16MB partition on a zip disk,
using mtdblock and blktmd. I accidentally typed "mount /mnt/flash"
rather than "umount /mnt/flash", and "mount" is now hung. Unkillable.
/mnt/flash is still mounted and usable, but not unmountable. It seems I
will have to reboot to umount the filesystem. I can't even eject the zip
disk.
