nvidia_drm error at the end of kernel ring buffer (dmesg)

[Tolga Durak]

Recently, I have noticed an error about nvidia_drm logged several times on my kernel ring buffer output occasionally.

I am using the Nvidia driver version 470.82 on Ubuntu 20.04.03 LTS with kernel version 5.11.0-40-generic.

My graphics card is RTX 2070 Mobile and I am using it via external G-SYNC monitor.

Some output log describing the error from dmesg command:
