Hard Systemwide Freeze on KDE Plasma

Issues & Assistance
1

For a while now I have been experiencing hard lockups on KDE, the system will completely freeze, no mouse movement, no animations, everything is unresponsive & I have noticed unplugging and re plugging things in power is not given to them. There is no notable journal errors except for “Applying output configuration failed!” and “Disabling IRQ #16” I have noticed it only happens on the desktop and after I close games.

Tried solutions:

Switching kernels (including LTS, no avail), updating system, editing kernel parameters, keeping PC cool it tend to has an overheat problem. Unplugging things in the room including USB just anything in real life, also switching to X11.

I had the same issue with my 13900K System, RT Bore Kernel fixed it or the new 6.18.3 Kernel with all the MESA Updates fixed it

Do you mean that specific kernel or the version? because I do have BORE installed, and it did it before. Going to switch to the regular bore now.

Just to mention .. there is a common misconception out there that realtime kernels might somehow be desirable for regular or gamer systems.

This is not true and an RT kernel may actually perform worse for those applications.

They are more appropriate for things like audio production and if you do not know you specifically need real-time for a specific use-case then you probably do not want it.

Also did not realtime become an option so we dont need special kernels for it anymore?

Just switched to bore… it froze even sooner. Might just have to switch DE’s. Although I dont know how to go about that and removing the rest of the packages. cant get the output of journalctl, but plasmashell and Xwayland crash dumped, along with “Invalid framebuffer status: “GL_FRAMEBUFFER_UNSUPPORTED” “Invalid dmabuf-based wl_buffer” although this was part a game, it might just be my hardware at this point

I didn’t picked RT-Bore for gaming reasons, it was just for searching how to fix my annoying problem. Had to do some research, that it’s normally intended for robotic systems and stuff. But it helped.

My Problem was finally fixed with the new 6.18.3 Standard Cachy Kernel with all the MESA Updates.

What we often forget is that “regular” Linux kernels can also serve as a reference.

Disregard the last post, the freezing overrall seems to relate to BTRFS and its snapshots. Ive turned of all forms of snapshots in btrfs assistant, going to test it from now on. Last froze had page flip timing out error, aswell as plasma crashing again. I am now in a loop of freezing, with the same error in journalctl:

So it was just a repeating message in BIOS: “usb set interface failed (-28)” something like that. I had saw this before but didn’t know how to go about fixing. Just switching USB ports and unplugging worked.

11 
$ errno 28
ENOSPC 28 No space left on device

I wonder what the original problem is, then.
