Hello!
I have problem with suspend: my PC trying to go to suspend mode, but after a few second tern back to lock screen.
I’m using desktop Fedora Workstation 37, Gnome 43.2, X11. My PC is Intel core i7, Nvidia GTX750ti (driver version: 525.60.11). I have tried X11 and Wayland — in both the same problem. I have tried to close all programs before suspend, and I’ve tried to logout from current user shell. It’s did not help too.
My journalctl has error:
systemd-sleep: Failed to put system to sleep. System resumed again: Device or resource busy
and dmesg has:
Freezing of tasks failed after 20.007 seconds (0 tasks refusing to freeze, wq_busy=1):
Showing busy workqueues and worker pools:

I don’t understand what the problem: Is it system bug or my OS settings wrong?
Is any possibility to look more informative logs data to fix it?
