Either your PM-Timer isn't running at the right frequency, or something is going wrong in the calibration. I'm suspecting its the second. If you add a "return 0;" to the top of verify_pmtmr_rate() in drivers/clocksource/acpi_pm.c does the acpi_pm timer keep proper time? 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/
