>Description:
On HP nx6110 (intel 910gml chipset, celeron-m) and ACPI enabled:
When system temperature raises/drops above/below hw.acpi.thermal.tz0._ACx levels the system freezes. The system freezes before the system fan gets switched on/off by the event. If the system is compiled with 4BSD scheduler, the freeze will last forever, with ULE scheduler, it is just a few seconds long. It is caused by an acpi (irq9) interrupt storm. With acpi disabled, the system works perfectly.
>How-To-Repeat:
Take HP nx 6110 laptop. Get freebsd with acpi compiled in and arange so that the system temperature raises/drops over _ACx levels.
