Hi,
You can recreate the bug if you have a kernel with modules support for
hfs-format, mount a hfs formated floppy and try to remove a file on that
floppy. You'll get a segmentation fault and an uninterruptible sleep for
the mount PID.
You cannot use or unmount the drive again. Because I've two floppy
drives I don't know if this is also the case if you have only one.
Regards
Wolfgang Pichler
