Hi Atanas, It looks like a link speed negotiation error. can you set the link speed to 100MB/s and see what happens. I don't think it is a driver or server hard ware issue but more and switch issue. Have you tried another switch or hub I use the same board in Servers and Gateways with FreeBSD and OpenBSD without any issues.
