From what i understand up to now, my problem wasnt that the controller
triggered an interrupt with NIEN set, but that the handler was returning
it as not handled.
Essentially that is what happened. Albert's patch simply fixed it
another way.
ATA is a bit annoying in that, we try to "know" when an interrupt is
expected. There is no 100% solution that simply allows us to check for
pending interrupts, without side effects.
Thus the explosion when unexpected interrupts are received.
