It worked for a while, but recently, having acpiec enabled
(with the patch above) results in

acpitz0 at acpi0: critical temperature 115 degC
acpitz1 at acpi0: critical temperature 105 degC
acpitz2 at acpi0: critical temperature 112 degC
acpitz3 at acpi0: critical temperature 112 degC
acpitz4 at acpi0: critical temperature 90 degC
acpitz5 at acpi0: critical temperature 112 degC

at boot and the system shuts down (correctly).
So I had to disable even the patched acpiec again.

Is anyone experiencing the same? Is there any point
upgrading to a 4.7-beta snapshot in this regard?

	Thanks
