Can anyone seeing this problem, if you're on the 3.13.0-71-generic kernel, please load the above attached module? It will initially check the node/zone start/end locations for validity, and also will check every time move_freepages is called, and if it detects the BUG() will be hit it prints out debug about the current node/zone values - but it doesn't prevent the BUG() so you'll know when the problem reproduces.
