I did not have the opportunity to investigate the software. I 
tried moving the network interface to a PCI board that works
fine in another machine, the interrupt storms remained.

I swaped the machine itself and the interrupt storms disapeared
with the same software, hence the culprit was the machine's
motherboard.
