It'll be this weekend, but I can see cases where it can lock my chip up
-- they should be rare, but then I thought your case would be extremely

I think we'll need to go to a full separation between MSI and
level-triggered interrupt handlers, or at the very least mask everything
and handle it all in NAPI. That seems more viable now that I know
Francois is not terribly worried about diverging from the vendor driver
