    Write ordering trouble shouldn't crash the kernel, the way I
    understand it. Your journalled fs could be lost/inconsistent
    if the machine crashes for other reasons, due to bad write
    ordering. But the ordering trouble shouldn't cause a crash,
    and all should be fine as soon as all the writes complete
    without other incidents.
