Hi all,

Last nights boot tests on various PowerPC systems failed like this:

calling  .numa_group_init+0x0/0x3c @ 1
initcall .numa_group_init+0x0/0x3c returned 0 after 0 usecs
calling  .numa_init+0x0/0x1dc @ 1

---[ end trace 31fd0ba7d8756001 ]---

swapper/0 (1) used greatest stack depth: 10864 bytes left
Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b

I may be completely wrong, but I guess the obvious target would be the
sched/numa branch that came in via the tip tree.

Config file attached.  I haven't had a chance to try to bisect this yet.

Anyone have any ideas?
