We've tracked this down to a problem where the nodeid might be invalid. Kamalesh
is investigating problem. We suspect we are doing a kmalloc_node with an invalid
nodeid.

We see

cpu with no node 2, num_online_nodes 1
cpu with no node 3, num_online_nodes 1

in the bootlog. Kamalesh verified that the problem exists with both slub and slab.
