Sorry, one more clarifying point here: When you used either clocksource=hpet/clocksource=acpi_pm did the behavior of the system seem different after booting? In other words: does running time waiting a few seconds and then running time again show the expected passage of time? Were any following hangs seen, or was it only the first one at boot? thanks -john -- 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/
