 Weird. We had a problem with a e1000 in one particular PCI-slot were the 
 NIC was dropping packets no other clues. Decreasing PCI-bus speed from 133 
 to 100 MHz solved this problem. There are two chip revs. Anvik I and II.
 Anvik I had problems in some architectures from what I understood.

 Cheers.
