Is it a Cisco Catalyst switch? If so, you need to switch the em's to autoselect, on both the server and switch end. For some reason, the em driver will not properly lock down its rate when talking to a Cisco Catalyst switch. At least, I had an identical problem with em's talking to a Catalyst 2950 and that was the fix I came up with. Give it a try and see how your results go.
