I have been doing enough CPU offline/online test these days and it works fine. But there is no cpufreq driver which supports my machine. So my test didn't cover test cpu hotplug code in cpufreq. If you have cpufreq driver and it is built as module, it is worth trying same test after unloading cpufreq driver in order to narrow down the problem area. - 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/
