You're running into the (in)famous ethtool vs autonegotiation issue. If you do ethtool -s eth0 autoneg off speed 10 duplex half I think it will probably work. The behavior you're describing applies to most drivers I think. I actually vote that we get ethtool to automatically turn autoneg off when someone forces speed _and_ duplex, as its always the right thing to do. Anyway, good luck. Jesse
