The bug is here:

https://bugzilla.kernel.org/show_bug.cgi?id=42673


If I can figure out exactly what NIC it is I'll try to get one
and see if I can reproduce the problem on my machines.  It's always
possible it's a bad interaction with some specific
motherboard(s).  I don't have a bus analyzer, but if I
can reproduce it, likely others can as well.

Thanks,
Ben
