I have an issue with Intel network card 82583V(e1000e driver),the ethernet port detect Hardware Unit Hang and reset unexpected. It seems to occur after few hours during high traffic on the interface. Sometimes the ethernet port go down and never recovery. I tried the latest e1000e driver from Intel(e1000e-2.4.14) ,but the issue is still exist. I attached message to this issue.<br />
<br />
Example error from message:<br />
