I'll cook up a patch for pata_macio that keeps the irq disabled until the first taskfile is fired. We don't share interrupts on those guys so it shouldn't be a big deal, we'll see if it helps with Mikael's problem. For the more "generic" case, I think you are stuffed when shared interrupts enter the picture. We'll see if you still get reports of such interrupt storms, when they happen ...
