It seems to mostly happen when I'm away from my desk. I come back to black screens that can't be awoken. It may be related to the displays going to sleep, but I'm not sure. I can still ssh into the box when it occurs, but trying to reboot the box remotely seems to just hang. Unfortunately, I don't have serial console set up on this machine.
Patch posted to dri-devel and the DRI maintainers. We'll see what they say! https://lore.kernel.org/dri-devel/20230413111254.22458-1-jlayton@kernel.org/T/#u
I seem to have come across the same bug (at least the stack trace looks almost identical). I saw this behaviour several times in the past weeks but can't reproduce it reliably. The last case happened as follows: - My Thinkpad T14 (AMD) is connected to a Thinkpad Hub through USB-C which is connected to a display through Display Port, additionally another external display is connected through HDMI directly to the Laptop. - The Laptop lid is closed as well - I unplug the USB-C Hub and HDMI connection in quick succession - When I later opened the lid, I had a blank screen I expected my Laptop to go into sleep, which did not happen. Trying to switch to a TTY didn't work and I had to force the machine to power off.

As your solution was accepted upstream 6.4 (54d217406afe) I've nominated it for stable 6.1.y and 6.3.y. https://lore.kernel.org/stable/1c04a328-10e2-606a-c1ab-370d785d3534@amd.com/T/#u I think this should be pulled into Fedora kernel sooner though than waiting for those to land if possible.
That sounds great to me. I hit the same bug as recently as June 29th.
This message is a reminder that Fedora Linux 37 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora Linux 37 on 2023-12-05. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a 'version' of '37'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, change the 'version' to a later Fedora Linux version. Note that the version field may be hidden. Click the "Show advanced fields" button if you do not see it. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora Linux 37 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora Linux, you are encouraged to change the 'version' to a later version prior to this bug being closed.
Fedora Linux 37 entered end-of-life (EOL) status on 2023-12-05. Fedora Linux 37 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora Linux please feel free to reopen this bug against that version. Note that the version field may be hidden. Click the "Show advanced fields" button if you do not see the version field. If you are unable to reopen this bug, please file a new report against an active release. Thank you for reporting this bug and we are sorry it could not be fixed.
This bug still seems to be a thing and I can recreate it pretty much to order just by one of powering off my screen disconnecting the displayport cable switching ports on my ATEN KVM to a different machine https://bugzilla.redhat.com/show_bug.cgi?id=2265233
