2.6.19 and up to 2.6.20-rc2 Ethernet problems x86_64

I first saw the problem on the 64x2 box after upgrading to 2.6.19. The
network appeared OK with ifconfig and route -n, but I had no network
access. Pinging any other box, the box was responding, but no response
was received by the 64x2. I checked cables and the switch which were OK,
so I figured I had a faulty receiver on the on-board ethernet. I plugged
in a PCI eepro100, reconfigured the network and it's been fine ever since.

I upgraded to 2.6.20-rc2 (also 2.6.19 and later) on the x86_64 laptop
and that also experienced the same problem - different cards in both
boxes. Downgraded to 2.6.19-rc5 and network is up.

Boycie sees just a few packets occasionally when pinged from barrabas,
but says its dropped no packets.

Also strange, I can scp a file from Boycie.
