Pls try this patch,

--- acpi-2.6/drivers/acpi/thermal.c~remove_queue_work 2004-11-10 23:38:51.693022464 +0800
+++ acpi-2.6/drivers/acpi/thermal.c 2004-11-10 23:39:50.195128792 +0800
@@ -472,6 +472,7 @@ acpi_thermal_critical (
printk(KERN_EMERG "Critical temperature reached (%ld C), shutting down.\n", KELVIN_TO_CELSIUS(tz->temperature));
acpi_bus_generate_event(device, ACPI_THERMAL_NOTIFY_CRITICAL, tz->trips.critical.flags.enabled);

+ tz->zombie = 1;
acpi_thermal_call_usermode(ACPI_THERMAL_PATH_POWEROFF);

return_VALUE(0);

Is this work?
