After a fresh install of Ubuntu server 16.04.4, the system shuts down fine with
sudo poweroff but hangs completely after :
sudo systemctl reboot or
sudo shutdown -r now. It doesn't matter if the command is launched via SSH or local session.
I tried to add
acpi=force as GRUB option, I tried to disable the swap but nothing worked so far.
Here's the displayed message as a picture. I think it happens too late during the process and isn't logged anywhere :
Possibly relevant lines could be :
systemd-shutdown: failed to finalize DM devices, ignoring ... general protection fault: 0000 [#11] SMP ... Code: Bad RIP value. ...
Do you have any idea what the problem is or what a possible fix could be?
