I'm confused. As I said in previous mail please check network cables such that down-shifting wouldn't take part in this issue. If that does not fix the issue, force speed/duplex on both ends. > As a reference the MB's affected by this are mostly the ASUS MB's, i.e. > P5B and P5K series ones.

Capture traffic on Mac with tcpdump and give me a URL for the pcap file. Btw, it would be even better if you can show me the PHY driver (e1000phy(4)) information in dmesg output. -- Regards, Pyun YongHyeon
