    What is strange about my configuration? Just that I enabled the
    RCU boost and other new RCU features?

    Surely it's not that I'm just doing lots of mounts and unmounts
    and file-io with lots of processes....

    And I was posting lockdep warnings on this since -rc1 or so, though granted
    I was running a few extra patches and having other bugs at the same time....

    Thanks,
    Ben
