Can you please post the output of dmidecode? We have a tool that you can use to dump the registers from the port in the failed state: http://sourceforge.net/projects/e1000/files/Ethregs%20-%20Register%20Dump%20Tool/ethregs-1.12.3/ I have not been able to reproduce any of the issues you reported on T60 here in the lab, so we need to start looking into more details. Also, could you please file a bug at e1000.sf.net with all the information you provided so far? Thanks, Emil
