    Subject[BUG] hotplug cpus on ia64
    Gentlemen,

    I built an ia64 kernel from Andrew's tree (2.6.26-rc2-mm1)
    and get a very predictable hotplug cpu problem.

    billberry1:/tmp/cpw # ./dis
    disabled cpu 17
    enabled cpu 17
    billberry1:/tmp/cpw # ./dis
    disabled cpu 17
    enabled cpu 17
    billberry1:/tmp/cpw # ./dis

    The script that disables the cpu always hangs (unkillable)
    on the 3rd attempt.
    I haven't spent any debugging time on it yet.

    Just wondering if you've seen it? It doesn't seem to happen x86_64.
