    I know I am late reporting this but I didn't figure it out until late
    this afternoon. I had trouble booting this one on my SMP workstation at
    the office. It would hang after it had almost finished booting. Anyway
    the solution was to disable tracing in /etc/rc.local and then re-enable
    it after it has finished booting. I know this happens late in the boot
    but it works for me.

    echo 0 > /proc/sys/kernel/trace_enabled
    #echo 0 > /proc/sys/kernel/preempt_wakeup_timing
    #echo 50 > /proc/sys/kernel/preempt_max_latency

    To be honest I am not sure which of the above fixes the late boot hang
    and I didn't have time to figure it out either. This doesn't happen on
    my SMP system here.
