[Bug 1497428] Re: kernel BUG at /build/buildd/linux-3.13.0/mm/page_alloc.c:968


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.
