I'm no good in reading ppc oopses but I'd guess we're trying to allocate memory on node 0 that doesn't have any of the necessary data structures set up? Btw, Nick, I applied the patch already: http://git.kernel.org/?p=linux/kernel/git/penberg/slab-2.6.git;a=commit;h=908fdd91ff07a2cb5fb316060f302c22080a23c9 so any fixes for Stephen's case needs to be on top of that.
