Start the machine in level 3, then login as root and issue "systemctl hibernate".
If it fails, extract the logs just at that instant.
The command triggered a full reboot after blanking the screen.
It would help if you say at what exact hour:minute:second you issued the command.
There is a warning about '/etc/init.d/xfs'. What is that? Ah, font server. Why has it not been migrated to systemd? Not related, anyway. It seems the hibernation command is given at "14:18:03". It seems to try hibernation, then stops and restores instantly at 14:18:49. No idea why.
It appears a successful hibernation followed by successful restore. I have no idea what is going on. Did you report in Bugzilla? I can tell you the same they told me once: Could you try hibernating directly via kernel interface: echo disk > /sys/power/state instead of systemd? If the problem is seen there, it's a bit easier to see what happening. The next step would be testing as described in Documentation/power/basic-pm-debugging.rst -- Cheers / Saludos, Carlos E. R.
