(In reply to O. Hartmann from comment #6)
NOCLEAN (and ccache or alike, if you're using) on rolling back could harm here.

At worst, `rm -rf /usr/obj/` is needed. I've bitten by this worst case before
(unrelated with nvidia GPU drivers). I've struggled with bi-sectiong before,
until
I've noticed about this problem.

This is because "linker_load_file: /boot/modules/nvidia-modeset.ko -
unsupported file type" usually means mis-match in (interface) versions between
actual kernel and kernel modules.
