As the laptop uses Optimus and I don't need the enanced graphic,
the NVIDIA hardware is always switched off.
So I don't have any problems using the laptop.

The kernel is a selfcompiled vanilla kernel using the git repository.
If I remeber correctly, the message started with the 5.11 kernel.

If you need more information, feel free to tell me what you want to see.
