The interrupts in question are specifically related to the transport
stream.

Yuk. I see what you mean. I don't think I really want to go that far.
The fix is minor so I don't mind patching kernels for my own use
when they get upgraded. If I start getting other problems as a consequence
I may just give up on the card but fingers-crossed it's working OK
for now.
