Did you try using the DEBUG_PER_CPU_MAPS option? This should trigger on any use of the node_to_cpumask map before it's been allocated. (Hmm, I should check if it also validates the node number - as when MAX_NUMNODES is used instead of nr_node_ids.)
Also, could you send me the config file and a short description of what kind of system you are testing on?
Thanks, Mike
