Looks like the retpoline validation complaining. Retpolines are a workaround to mitigate the Spectre v2 CPU speculation side-attack channel. [1] The validation checks compiled object files for the proper return instruction sequence. I have no idea whether this is expected or not, since I don't use the nVidia drivers, but I would check if the involved packages are up to date. The driver looks fine (just to make sure, check the version of nvidia-driver-G06-kmp-default specifically), but check that kernel-devel and kernel-default-devel match your kernel version, and gcc is up to date. Not sure if anything else might be relevant. Also, did you do any changes related to CPU vulnerability mitigations? If everything is up to date, I would suggest to file a bug. The mailing list isn't the right place for such a specific issue that doesn't break anything. Aaron [1] <https://en.wikipedia.org/wiki/Spectre_(security_vulnerability)#Mitigation>
