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.
