No response to Alt-SysRq keys. No messages on the serial console (other than those showing a normal boot / telinit 5). Kernel was PREEMPT_RT plus a patch to profile on NMI, not timer (been using this latter one for some time). Basically same .config as previously provided but can send if needed. Boot parameters included serial console, profile=2, nmi_watchdog. Will retry shortly, but the steps leading to the failure were: - boot single user - telinit 5 - su'd 3 times - created directories to log data / moved some files around - set IRQ threads, ksoftirqd/[01], events/[01] to RT fifo 99 priority - started two monitoring scripts (looking at latency & profile data) - cat /proc/sys/kernel/preempt_wakeup_timing (was 1) - echo 0 > /proc/sys/kernel/preempt_wakeup_timing [entered, but display was frozen at this point and did not see newline nor any further output] --Mark H Johnson - 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/
