Nothing obvious in the logs.

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…

5

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

6

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.

Same problem with Ubuntu 22.04, latest drivers from NVidia repos (see package details below) and using Xorg.
It starts consuming 100% of the CPU until I restart the services, but after sometime it starts to consume 100% of CPU again.

It is a Lenovo P1 Gen 4 with the following NVidia card:

NVIDIA T1200 Laptop GPU
01:00.0 VGA compatible controller: NVIDIA Corporation TU117GLM [T1200 Laptop GPU] (rev a1)

I have the Intel GPU disabled, but it also happens with the Intel GPU enabled.

I’m using the laptop monitor and two external monitors with the Lenovo Thunderbolt 4 Dock (also tested with Lenovo Thunderbolt 43 Dock): Screen resolutions (basically 1920x1080 and 1920x1200 on the laptop monitor):

$ xrandr --listmonitors
Monitors: 3
 0: +*eDP-1-1 1920/345x1200/215+1920+0  eDP-1-1
 1: +DP-0.1.5 1920/477x1080/268+0+120  DP-0.1.5
 2: +DP-0.2 1920/477x1080/268+3840+120  DP-0.2

The power settings, from Nvidia-settings application are set in “Auto” mode.

Same issue with Mint 21.1, I addressed it with a cron ( */1 * * * * /path/to/script.sh > /path/to/script.log 2>&1 ) calling this script :

#!/bin/bash
nvidia_usage=$(ps -C nvidia-powerd -o %cpu | grep -v C | awk '{printf $1}' | cut -d "." -f 1)
if [ "$nvidia_usage" -gt 5 ]; then
    systemctl restart nvidia-powerd
    echo "nvidia-powerd service KO => restarted"
else
    echo "nvidia-powerd service OK"
fi

I hope that helps, waiting for a fix as well.
I noticed this behavior since cuda install a few days ago.
