@jmerrilljr once more thing that might help: if you can test all of the 4.19-rc test builds (there were 8, rc1-rc8) it might help narrow down the range that includes the breaking commit. You can find links to the 4.19-rc test builds in PR2937. Start with 4.19-rc1 and if that doesn't have the problem then test the next release ie. 4.19-rc2. Post which release of 4.19-rc is the first with the problem. Thanks.

Also, can you describe what your PC is connected to - what type of cable (CAT5, CAT5e etc.), what type of switch (make/model/brand).
