It’s this line where the kernel notes why it is tainted.  Somewhere in the nvidia kmod C code, there is a line that looks like this:

MODULE_LICENSE("NVIDIA"); 

The kernel will print out the aforementioned kernel message if it isn’t one of the open licenses defined in the kernel.  There’s more about tainted kernels here:


There are a variety of reasons why the kernel would be tainted, but in this case it is because a proprietary kernel module was loaded. It doesn’t have anything to do with signed kernel modules or secure boot. 

I thought the akmod version of the nvidia driver was the version that was compiled every time the kernel version was changed, is that not the case?

Steve
