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:

Meanwhile, the system log shows:

What are these errors even talking about, what is the cause, and possible solutions?

Thanks so much!

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.

Did you really build the module yourself? It doesn't even seem
you have kernel headers.
