In this specific case, the problem is clearly due to nonsensical code in the DSDT that alters the thermal trip points based on ioapic configuration. It's only been observed on two almost identical models from one manufacturer, and doesn't occur on any other known machines with the same chipset. I think it's safe to special-case. -- Matthew Garrett | mjg59@xxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
