The problem is that recent binutils versions strip undefined symbols from vmlinux. Normally a ppc64el kernel has the following undefined symbols: | 44809: 0000000000000000 0 NOTYPE WEAK DEFAULT UND mach_powermac | 52870: 0000000000000000 0 NOTYPE WEAK DEFAULT UND mach_chrp | 62021: 0000000000000000 0 NOTYPE WEAK DEFAULT UND mach_cell | 62383: 0000000000000000 0 NOTYPE WEAK DEFAULT UND __crc_TOC. However this is not the case anymore. This is due to the following change on the binutils side: | commit d983c8c5503d680c6d4955ceb610a9beebc64460 | Author: Alan Modra <amo...@gmail.com> | Date: Wed Feb 18 17:02:39 2015 +1030 | | Strip undefined symbols from .symtab | | bfd/ | PR ld/4317 | * elflink.c (elf_link_input_bfd): Drop undefined local syms. | (elf_link_output_extsym): Drop local and global undefined syms. | Tidy.

I am not sure the powerpc and ppc64el are actually due to the same bug in binutils. Aurelien -- Aurelien Jarno GPG: 4096R/1DDD8C9B aurel...@aurel32.net http://www.aurel32.net
