I experience same after adding a new SATA drive and extending the VG ang LV. I get the "Systemd-shutdown: Failed to finalize DM devices, ignoring." message after "shutdown -h now" or "shutdown -P now" command and right after a "click" sound from the computer case. I have to manually reset the computer. The computer reboots fine.
