More Info

No response

Start with the reported make modules -j8 CC=gcc TARGET_ARCH=x86_64 NV_VERBOSE=1 command and the failure in scripts/Makefile.modpost. Inspect how Module.symvers and the listed NVIDIA and DRM symbols are produced during the Ubuntu 20.04/Linux 5.18.12 build. Done means the modules build without the reported undefined-symbol errors.
