Perhaps it's not re-evaluating zones and disabling one that is now inactive once the machine is unplugged. The number of zones (acX) can change when power state changes. Then it gets an invalid reading and thermal trip occurs. Put debugging prints in the acpi_thermal re-evaluation code. > The last issue is that like some other folks the system will lockup if I > let powerd bring the clock down when idle.

It depends what drivers your system is using, dmesg | grep cpu. -- Nate
