Nvidia-powerd using lots of cpu on fedora 35 running gnome on wayland

Nothing obvious in the logs.

$ rpm -qf /usr/bin/nvidia-powerd

Let me know if there is anything else I can provide to help troubleshoot.

Same problem in Fedora 35 X11 plasma session. After system start all was fine, but after I played some games nvidia-powerd started to consume 100% of one thread and stopped only after I restarted it (games were not running already, but daemon kept consuming cpu until restart).

UPDATE: it also eats 130MB of memory.

Same problem in Fedora 35 X11 gnome session. At some point nvidia-powerd starts to consume 100% of one thread. Can be worked around by restarting the nvidia-powerd, but sooner or later it degrades again.

Same problem for me as well, using Fedora 35 with the i3 window manager. I can restart nvidia-powerd but after some time it goes crazy again…

Does anyone have any temporary fix to suggest? E.g. a bash script that monitors whether the process gets stuck and restarts it automatically?

Same problem with Fedora 35 on Lenovo Thinkpad P1 G4. I “solve” it by killing nvidia-powerd after each general reboot.
From root I do “killall nvidia-powerd” . Then suspend and hibernate work as expected and CPU usage is no longer crazy.

Problem persists in Fedora 36, very annoying.
