Right. However if this is what Thomas was seeing the problem turned
out to be an issue with pci_enable_device changing the irq number.
It just happens that now the code cares, so the bug is found.

Marcus any chance I could see an oops? Or you could try the patch I
previously posted when debugging this with Thomas.

I'm going to clean that patch up and send it along in hopes that it
helps anyway and see where we land.
