If the problem still occurs with the latest 2.6.31-rcX, I should try and/or use the latest e1000e driver from here: http://sourceforge.net/projects/e1000/ -- aside from that, are there any other workarounds (if the problem persists)? I have used the same cable with 3 different NICs (two x1 PCI-e) and the last system I had was PCI-e (on-board) all negotiated 1gbps, this one though only negotiates at 10mbps duplex. Is this a known bug?
