there is no crash visible in the logfile. it's also not visible what exactly happens so that you "get no ethernet connection".

(In reply to Thomas Haller from comment #1) Yes, no actual crash but a failure. Look at May 2 18:43:34 server1 systemd[1]: NetworkManager-wait-online.service: Main process exited, code=exited, status=1/FAILURE Seems to be due dhcp can't get any data. see: Logs, dhcp, nmdb and NetworkManager 4.15.17 and 4.16.5.log Question is why it is working in 4.15.17 and not in 4.16.4/4.16.5.
