    In the deadlock we are seeing, _someone_ is waiting on userspace
    thread, that leads to deadlock with freezer. We don't know who,
    because we have not seen the sysrq-t dumps.

    The "unknown who" will deadlock on fused frozen by driver, too. We
    really need to fix the "unknown who" here.
