Ubuntu 22.04 resumes from hibernation instantly

[ViBE-HU]

@slaclau as you requested now I report the issue. "Sadly" it looks like it is not related directly with the extension itself because systemctl hibernate does not work either. I have and AMD+NVIDIA laptop. The following happens:

1. Hibernation starts
2. Displays goes off
3. Suddenly the system came back after 5-6 secs

I have to mention that I use my machine docked with external peripherals. I set the machine to do nothing when the lid is closed. The hibernation function and the extension works well on my other laptops except this one.

Can you post the output of this command please; sudo journalctl -u systemd-hibernate.service

Sorry for the late reply:

Now seeing this log I must tell that the swap size should be enough. It is 29 GB. I always set the "With hibernation" size. I have 24 GB RAM in that machine and the system hardly ever (maybe never) swapped anything. Swappiness set to very low. I have a long term routine to fix hibernation on Ubuntu machines and I have actually 3 machines with Ubuntu 22.04 and one with 24.04. All configured the same way and all capable to hibernate itself by using your extension except that exact machine.
