[Imre Péntek (pentek-imre)]

what happens is ethernet keeps working, but once every 2-3 days it just stops, and the way I fix it is I unplug the usb3->usbc adapter (which connects to the usbc->ethernet adapter)

[Imre Péntek (pentek-imre)]

... then I plug it right back in

I think the dmesg issue might be related

Hi,

I had the same issue, what happend is that the network went down and the server flooded the switch with traffic.
