Hi! I've been having a problem on my Acer Swift 5 SF514-54T laptop where it isn't able to shutdown or reboot after having been suspended at any point during its uptime. It hangs on a black screen and I have to put it out of its misery by manually holding the power button to complete the shutdown. Shutting down and rebooting works perfectly fine if the machine hasn't been suspended since boot. I am running Fedora Silverblue 32. Since I have no idea what could possibly be causing this issue, I'm not sure what other info to provide, so please do ask me if you need any further information. Thanks in advance!

Hey,
I let this one sit a little but before it sinks down I want to reply although I have nothing very helpful to say.

This laptop is pretty new; I think I saw a notebookcheck review from this year, i.e. 2020.
You are currently running one of the few distros that even makes sense on such a new device (Linux always needs a while to catch up with new hardware, but Fedora incorporates new developments very early).
I don't know Fedora but I use ArchLinux, it is another distro that might possibly work on this device.

There's of course the option to hunt down the problem and hope it's solvable.
Start with checking the journal for meaningful messages.

Can you shut it down manually with a "shutdown -h now"? (Might be "shutdown -p now" or "halt" or some such on Fedora...)

Thank you for your response! This laptop is indeed quite recent, but if possible I'd like to find the problem and report it in order to improve the experience for everyone.

I checked the journal and the last message displayed before the system hangs seems to be from a kernel audit. Another possibly meaningful message I could find is but unfortunately searching on the internet for this string yielded me no useful results.

Same problem there, unfortunately. It hangs on a black screen before completing the shutdown.

OK, then (after a reboot) look at the journal for around that time.
Just show us all the entries from the moment you enter the command.
BTW, you might want to use "poweroff" or "systemctl poweroff" instead.

Hihi. Don't you like variety .

Sorry for the delay - I'm currently traveling, so my Internet connection isn't incredibly reliable. However, I seem to have a pretty stable connection right now, so I put the relevant logs on Pastebin.

Sorry, that is way beyond me.
I went through the output, there's nothing that clearly says "I hang".
Maybe some ACPI problems, you can try some common ACPI troubleshooting methods, temporarily add some command line switches etc.
Maybe gnome-shell crashing has something to do with it, but since the shutdown process continues after that it could only be indirectly.
Of course you're using a bleeding edge distro. Have you looked around their forum?
