The question is whether ath_hal_intrset does work or not. If it doesn't
work correctly, you are right and ath will keep the interrupt "masked".
The idea here is that a PCI interrupt remains raised if at least one
device requests it. That's why it is safe to return 1 when the interrupt
is handled -- it will get reraised by the hardware.

Just to make sure, print the current interface flags -- is IFF_RUNNING
*not* set for you?
