As of v5.10 we now have merged commit 14721add58ef267344bee254bc276c9139b7b665
("module: Add more error message for failed kernel module loading")
which helps expand on this being more friendly:

That's from apply_relocate_add(). The locs are supposed to be
0 and they are not so it bails. That relocation type is 1 so
R_X86_64_64.
