Un-taint kernel

I have moved your post into a new topic, the original topic was created almost 4 years ago.

So, you are seeing the kernel taint message somewhere? Are you running nvidia drivers? can you please share the output of dmesg | grep -i taint? If you load nvidia drivers, I think the kernel automatically reports to be tainted because the nvidia driver is out of tree no matter what.
