Yeah, this is what I was expecting, it's tripping on

	VM_BUG_ON(nid < 0 || nid >= MAX_NUMNODES || !node_online(nid));

and slub won't pass nid < 0.  You're sure my patch is applied? :)

I did have your patch applied but at "b4cdf91 sched/numa: Implement numa
balancer" (where git bisect spotted the fail).  

If I apply your patch on the full next-20120521 it does fix the problem.

Sorry for the confusion.

Thanks!
