Strange OS freeze

[qrp73]

Describe the bug

I switched to the virtual terminal with Alt+Ctrl+F1 and played with text selection using the mouse and different combinations for copy/paste (I have installed gpm and clipman). Then I left it for 5-10 minutes, and when I came back, the system had frozen. It did not respond to keyboard input or SSH connections.

When it happened, there was a Firefox process running on Wayfire with 3 tabs open.

Steps to reproduce the behaviour

I don't have steps for guaranteed reproduce of the issue.

What time did you return to the system and find it frozen? Are any of those log entries likely to be relevant?

I return at about 21:45.

Here is additional chunk of log from other file:

Sep 11 21:47:12 raspi NetworkManager[856]: <info>  [1726080432.0349] agent-manager: agent[7ed80f3caaaf21b7,:1.31/org.freedesktop.nm-applet/1000]: agent registered
Sep 11 21:47:13 raspi systemd[1]: NetworkManager-dispatcher.service: Deactivated successfully.
Sep 11 21:47:26 raspi systemd[1]: systemd-fsckd.service: Deactivated successfully.

And it appears that this is the last records and no logs after 21:47:28 till the new boot.

When I returned it shown Wayfire desktop, I'm not sure for 100% but probably I leave it in virtual terminal mode, because I surprised that it shows desktop. But the system was completely unresponsive, mouse didn't worked, keyboard didn't worked. I tried to ssh login to check the logs, but it appears that it don't listen even for ssh connections.

I don't remember such freeze for a long time, so I suspect it may be related to virtual terminal, gpm and clipboard with different keyboard shortcuts, like Alt+W, Ctrl+C/Ctrl+V, Cttrl+B and [, Ctrl+B and ], and other, which I played before that issue.

Could this be related to #6349? You say "I don't remember such freeze for a long time", maybe the virtual terminal is just a coincidence and it's in reality the latest kernel update.
