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. kr - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
