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. -- Warm Regards, Balbir Singh Linux Technology Center IBM, ISTL -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
