What does ACPI claim the trip points are set to in this case? On the 6125, if IRQ 2 is enabled in the APIC then the DSDT sets all the thermal trip points to 16 degrees C. I suspect this means that enabling IRQ 2 is the wrong thing to do on this chipset. -- Matthew Garrett | mjg59@...f.ucam.org -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
