After coming back from the weekend, the issue is now also occurring on the 4.15.0-20 kernel. I am not sure what is up. I had tried the 4.15.0-22 and 4.15.0-36 kernels, prior to booting up 4.15.0-20 again. In this particular machine, I had tried resetting the power saving settings of the network card from a Windows install, per bug that could be related: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1785171
To make this issue ever more confusing, we have another DELL 7060 running 4.15.0-36 where the network card is working perfectly and the issue has not come up at all. >From my latest test on 4.15.0-20 and some discussion with TJ- in IRC, he asked me for some output to look at sysfs output from the card.
