Sometimes after trying to resume from the suspend state, I cannot reach the desktop, the screen remains black and the system appears unresponsive. This started happening after some of the recent updates, before that I didn’t have such a problem. I’ve checked journalctl logs but can’t determine the cause.
I’ll use an example from today with relevant parts from the logs. At 11:45 I locked my computer and left, and it was supposed to enter suspend at some point. Upon my return around 13:10, I couldn’t resume, the screen stayed blank. I tried multiple Ctrl+Alt+Del which is reflected in the logs, but I didn’t see any visible reaction to it, so I eventually forcefully terminated the system.

After the reboot, it reached the GUI login screen successfully an in reasonable time. The sequence is often the same: failed resume from a suspend, then unsuccessfull power-up, thenn successful reboot.
The full journalctl logs are available at github gist. It has three files, 1.txt for the last session before the failed suspend (it has examples of successful suspends as well), 2.txt is the session which I had to reboot because it got stuck on the splash screen, 3.txt is the session with a successful boot.
Also, maybe it’s relevant, as at least some part of the observed behavior seems to be related to network, but I noticed problems with my network quite a while ago: almost always after suspend or boot my network was initially down and then up ~40 seconds after. But it never caused any problems with the system not beeing able to boot/resume. Below is a log from January showing Network Manager behaviour after the suspent.
