Hi Folks,
Am seeing a crash on a power5 LPAR when booting the linux-2.6 git
tree. It's fairly early during boot, so I've included the whole log
below. This partition has 8 procs, (shared, including threads), and
512M RAM.

A bisect claims:
765c4507af71c39aba21006bbd3ec809fe9714ff is first bad commit
commit 765c4507af71c39aba21006bbd3ec809fe9714ff

[PATCH] GFP_THISNODE for the slab allocator

Am willing to dig deeper, but looking for pointers on what to poke next.

Thanks,
-Will
