Hi,
I could solve this problems in two steps, first I installed Debian to
get more information about the error, so this appears at the end...
systemd-shutdown[1]: Could not detach DM /dev/dm-0: Device or resource busy'
systemd-shutdown[1]: Failed to finalize DM devices, ignoring.
reboot: Power
I have a similar problem, see here for more information:
