    Well whatever bug it is, it's in Linus's tree now. Happens for me too.

    I traced the failure down as far as acpi_processor_get_performance_info(),
    where it's failing here:

    status = acpi_get_handle(pr->handle, "_PCT", &handle);
    if (ACPI_FAILURE(status)) {
    ACPI_DEBUG_PRINT((ACPI_DB_INFO,
    "ACPI-based processor performance control unavailable\n"));
    return_VALUE(-ENODEV);
    }
