We don't really care much about sync, and other crap that happens during
shutdown

Amd is trying to unmount a filesystem and is stuck in genfs_lock
And the million $ question is:
Is amd trying to unmount because of the shutdown, or because of the
periodic mount timeout? If the second, do we have a locking race
during unmount?
Unfortunately looks like you'll have to reboot and redo the test to
answer this.
