The problem continues with 4.15.0-65-generic. This is a ping summary
coming into the affected system from another host on the same network

This also occurs on wireless network connections, and *may* coincide
with my USB mouse seeing lessened throughput.
It appears to be weakly correlated with the amount of load on the
system. I see no evidence of it occurring at times when the system is
not in use.

Intermittently and unpredictably, ping response times and packet loss
