Hey Larry Thank you for the prompt reply. I am not a kernel dev. My intension was to seek help and understand how this impacts my system. I looked for removing the taint. However, it seems Nvidia driver is the one that is tainting the kernel. Since this is the laptop I use for work, I don't think I can remove NVidia driver. If I understand correctly, using the Nouveau driver instead the proprietary one should remove the taint. Is there any other way I can help ?
