We need more information to figure out why the kmalloc_node fails there. It should walk through all nodes to find memory. I see that you have 4 cpus and 16 nodes. How are the cpus assigned to nodes? If a cpu would be assigned to a nonexisting node then this could be the result. Could you post the full boot log? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
