Hi Burnat
I can do that but I have so little information, also bug report looks complicated, is there is any howto? to post a bug report properly

Finally using the A7N8X-Deluxe (3Com 920 and nForce2 MCP LAN) I was able to make it work properly.
3com920 was very stable but nForce2 MCP controller was not, the configuration page found it and I selected it, worked the first time and after reboot, eth1 == nForce2 MCP, was gone, after that, I can see it in the configuration page but doesn't start.
I tried ifup eth1 but no go, so it was time to add the old well known RTL8139 and everything is working now

I don't have anymore the A7N8X-Deluxe to do more tests on nForce2 MCP but I do have the previous Intel D945GCNL (82801, ICH7 with 8168 gigabit lan) to do some tests, if you want, tell me what would you like me to test and I can do it, it would be great if we can make it work.
Oh!, one other thing, just for the fun of it, I tried another mobo, Intel D945GCPE (82801, ICH7 but with RTL8101) and same problem, card isn't even detected.
let me know please if you want me to do some tests.
thanks
