I also encountered this issue on Kwin 5.26.5 Wayland on NixOS with AMD 6000
series. In my case, I usually use the iGPU of my Ryzen 6900HX processor (Radeon
680M). The `kernel: sched: RT throttling activated` kernel line seems to mark
the lock up, following a series of similar log snippets:

In this case, there was no kernel module traceback in logs, indicating it was
just kwin which seems to have entered some form of infinite loop.
