The edge triggered mode had a bug in the ISR code which was fixed 
probably 6 month ago. Under heavy traffic you will get more than one 
interrupt while processing the first one but only one edge is generated. 
As the driver did not check for any pending interrupts after processing 
the first one any following interrupts were left unprocessed and the 
network locked up as packets were not sent out.
