Describe the bug

Hi everyone,

After switching to the open driver I noticed my laptop (Lenovo Legion Slim 5 16APH8) does not enter D3cold, there are no processes running accessing the GPU at the time as this is after a fresh reboot. Running "watch -n 1 cat /sys/class/drm/card*/device/power_state" you can see that it's running constantly in D0 state, it switches for a second or so to D3cold, but immediately changes back to D0.

This issue is not present in the closed driver 565.57.01, after a reboot the laptop changes to D3cold after less than 30 seconds.

I only noticed because power consumption was higher than normal while on battery.

To Reproduce

Install nvidia-open-dkms package on Arch Linux

More Info

No response

Start by reviewing nvidia-bug-report.log.gz and reproducing the issue with watch -n 1 cat /sys/class/drm/card*/device/power_state after a fresh reboot. Compare the open-driver behavior with the confirmed-working proprietary driver on the Lenovo Legion Slim 5 16APH8. Done means the GPU remains in D3cold when unused and battery power consumption returns to normal.
