Just bought a ECS P4M800-M7 (V3.1), and had some problems on vr0 with 
FreeBSD 6.0.
Without carrier, system hangs. With cable plugged in, vr0 doesn't work 
properly.
Dhclient fails. Even manually ifconfig vr0 to a IP, machine cannot ping 
the gateway.
Plugged in a fxp0 NIC and dhclient works on fxp0.
So, I wonder if this vr driver issue or is it a bad NIC? (vr0 is on 
board NIC).
