This sounds similar to a problem I had with NetGear cards which was
diagnosed by Keith Owens.  It only manifiested itself on shared media
(i.e. hub not switch) and turned out to be that the arp-reply was never
making it into the NIC's Rx ring (instead there was a copy of the
transmitted packet).

1) Are you on a hub?

2) Can you avoid this by first pinging *to* (before has
attempted to arp)?

3) Does this silliness goes away if you put a static ARP entry on
