I can't think of any solution other than ack'ing and clearing interrupts
blindly while frozen.
* it only happens from the freezing point until the device/controller is
reset.
* we can't detect spurious interrupts during that period but nothing
else is lost. Also, please note that most traditional IDE controllers
tend to have their own IRQ.
