--- Comment #14 from Aleksandr Fedorov <aleksandr.fedorov at itglobal.com> ---
These messages looks to me as expected:

Feb 26 21:46:11 core dhclient[3521]: receive_packet failed on ngeth0: Device
not configured
Feb 26 21:46:11 core dhclient[3521]: ioctl(SIOCGIFFLAGS) on ngeth0: Operation
not permitted
Feb 26 21:46:11 core dhclient[3521]: Interface ngeth0 no longer appears valid.
Feb 26 21:46:11 core dhclient[3521]: No live interfaces to poll on - exiting.
Feb 26 21:46:11 core dhclient[3521]: exiting.
Feb 26 21:46:11 core dhclient[3521]: connection closed
Feb 26 21:46:11 core dhclient[3521]: exiting.


But these need further research:
Feb 26 21:43:17 core kernel: ifaddr cache = 0xfffff8000ddf5600 is deleted
Feb 26 21:43:17 core kernel: if_delmulti_locked: detaching ifnet instance
0xfffff80059e8b000
