It turns out that this causes all mannor of problems on certain
motherboards (so far with no pattern I can discern)

Problems include:
* Hanging forever checking hlt instruction.
* Panics when trying to change switch root device
* Drivers hanging when trying to check for interrupts.

This changeset needs removing from testing trees as well.
