I read an article here https://serverfault.com/questions/616485/e1000e- reset-adapter-unexpectedly-detected-hardware-unit- hang?utm_medium=organic&utm_source=google_rich_qa&utm_campaign=google_rich_qa which stated some people had had success preventing this by disabling hardware offloading with ethtool -K eth0 gso off gro off tso off. With the 4.15.0-21-lowlatency #22-Ubuntu SMP PREEMPT Tue May 1 15:47:42 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux kernel on the i7-6850 machine which has been the most problematic, I did this and have not had a hang since. Obviously this comes with a performance penalty so is undesirable as a permanent fix but hoping this might help narrow the cause.
