Why do I get unresolved symbols like foo__ver_foo in modules?
• (KO) If /proc/ksyms or the output from depmod -ae contains symbols like “foo__ver_foo” then you have been bitten by the broken Makefile code for symbol versioning. The only safe way to recover is save your config, delete everything, restore the config and recompile. Do this: mv .config .. make mrproper mv ../.config .
