Thanks. 

I'm tempted to just ignore it in this case, but in theory it might
still have troubles if there are a lot of interrupts to the same CPU.

I've only had a report on a very large system with a very high interrupt
rate on a very fast NIC though, so presumably it's not too common.

Anyways this patch will fix the problem for all drivers that do 
not explicitely enable interrupts, which is the overwhelming majority.
