Actually, this is a different bug with the same symptom. Applying the patch from Peter, and running it: $ ./.build_test_kernel-x86_64/tools/objtool/objtool check -abdJsuld .build_test_kernel-x86_64/vmlinux.o nr_sections: 15446 section_bits: 13 nr_symbols: 116448 symbol_bits: 16 max_reloc: 8031700 tot_reloc: 12477754 reloc_bits: 19 nr_insns: 2523443 .build_test_kernel-x86_64/vmlinux.o: warning: objtool: want_init_on_free()+0x0: jump-label unpatched This is against a freshly built kernel -- i removed the build directory, copied in a .config file and built a fresh kernel.
