network interface problem

I just loaded 7.1 and a recomplied the 2.4 kernel (with ipmasq and iptables support) and I am getting an error message for my second network interface. I can do in ifconfig and the interface is up but here is the message from /var/log/messages: Mar 17 19:14:43 lucky kernel: NETDEV WATCHDOG: eth1: transmit timed out Mar 17 19:14:43 lucky kernel: eth1: Transmit timed out, status fc124010, CSR12 00000000, resetting... I am using Linksys cards, I am having no problems with them on other systems and tried replacing the card. Any help / ideas would be greatly appreciated. TIA
