Sorry, I was being vague. Mel Gorman found a problem that appears
linked to the change to 16-bit apicids on an AMD box that has 4
nodes, but nodes 1-3 have no memory, and the system panics during
cpu_up() on the 2nd cpu which is on node 1.

I've not yet been able to replicate the problem.

Thanks,
Mike
