hang with disconnected Zip drive

I managed to wrap the power cable to my Zip drive around my foot. Then I
stood up. I then plugged the drive back in.

ls /zip/linux showed no files (wrong)
ls /zip showed a few directories (correct)

I pressed eject and the disk ejected (normally it's locked but presumably
the power-cycle messed that up). the umount /zip worked fine but the mount
/zip hung the machine.

Looking at /var/log/syslog after the reboot showed:
