This did not start until after the latest update… I
Any ideas how to stop this?
The RED interface is plugged directly into cable modem.

Hi Gavin,

Try the following:-
Login using SSH and use the following command:-
ethtool --set-eee red0 eee off

That should turn off the energy efficiency on the card.
Alternatively on your cable router, can you set the device to fixed speed and duplex?

If the above works you could add it to your /etc/sysconfig/rc.local file to set it on boot up.

This is most likely a broken Ethernet cable. Or the NIC got toasted.

Power Management is rather unlikely I would say.

I found that Adding igb.EEE=0 to kernel cmdline disables EEE durign boot.

5

And you can rule out that this is not caused by any hardware or firmware issue with this card?

Hi Gavin,

Did that solve your issue?

Michael, the reason I suggested it was I had read somewhere that some cable modems notable Netgear ones had an issue with power management and auto negotiation.

The issue resolved its self… and has not returned but I have another issue with one that is off site that seems to relate to this… I will update the post with what I find soon.

Thanks
