:Done. But now I rebooted 10 times without any problem. Go figure!

    What I believe is happening is that on an SMP system the second cpu
    is being stopped at a bad point in time, causing it to hold locks on
    one or more buffers or vnodes.  The first cpu is then unable to flush
    the related buffers.
