It looks like with changeset 8831 cpu_core_ids are no longer unique across phys cpus. So, when we search for siblings to populate cpu_sibling_map, just checking for same core IDs are not good enough. Both core ID and phys cpu ID have to match. Patch attached fixes this.
Thanks. It turns out all that code in smpboot.c disappeared in the latest 2.6 codebase, so I upgraded to that and the problem has gone away. :-)
