Hi Eric, If I run my tests with the 2.6.30-2-amd64 kernel the network doesn't=20 malfunction. If I run my tests with the 2.6.32-3-amd64 kernel the network does=20 malfunction. If I take the forcedeth.ko module from the 2.6.30-2-amd64 kernel and=20 drop that into /lib/modules/2.6.32-3-amd64/kernel/drivers/net/ and then= =20 reboot to 2.6.32-3-amd64 and rerun my tests - the network does malfunct= ion. > Are both way non functional (RX and TX), or only one side ? Whats the best way of testing this? (tcpdump listening on both hosts an= d=20 then running pings between the systems?) -stephen
