Looks like much better results.

At any rate, I would love to see the full output of just ptp4l running on the i217-LM without phc2sys and so forth interfering. Mostly I would like to get enough information to see if we can rootcause why that particular hardware was failing. You might try the out of tree sourceforge module for e1000e on the Intel e1000e sourceforge page, because it may (or may not) have bug fixes compared to upstream. I honestly don't know what state upstream e1000e is vs the source forge driver.
