Network interface trouble

[Limaunion]

Hello!

I'm having some kind of network interfaces conflict, can anyone point me 
in the right direction please ? I have another Ubuntu system in another 
disk partition (same PC & HW) and it doesn't show this problem (same 
kernel and configuration), what can it be ? I just want to bring up 
eth0=ne2k-pci and eth1=forcedeth.

dmesg:
(it seems there's a conflict, two eth0?, how can be solved?)
