I did a ctrl-alt-F1, logged in, then "sudo shutdown -h now" and there were some network manager messages but not the ones regarding "no debugging symbols found". The first was "NetworkManager: <WARN> nm_signal_handler():caught signal 15, shutting down normally". Then other messages as on the attached screenshot (literally).
