What about the GT interrupts? I just stuck stuff at the > bottom, figuring it would do the least harm... Thinking this through again I don't see the race anymore. I've forgotten that masking things in IMR also prevents stuff from showing up in IIR and hence a SDE irq after clearing DE irqs can't leave garbage behind in DEIIR. So no need to clear things in the order the irqs propagate, i.e. SDE->DE->GT.
