I haven't ever used mii-tools, but I have seen two things that can cause this: 1) If you made the crossover cable yourself, and you weren't extremely careful, you can get bleedover, etc. I have been burned a couple of times, so now I purchase them. Saves the headache. :) 2) I've had problems lately with auto-detect of duplex. I've gotten to the point where I specify full or half duplex, based on the NIC's switch, etc. In your case, you might want to try half-duplex on both cards, then when that works, try full-duplex and see what happens. Come to think of it, you might want to double check your router table also. You might need a static route stating that all traffic headed for your other machine *has* to go through that other NIC.
