[Bug 1497428] Re: kernel BUG at /build/buildd/linux-3.13.0/mm/page_alloc.c:968
The newer kernel may have some change/fix that prevents this bug, as I
haven't seen any reports of this (from google, at least) on any other
kernel. Plus, the unusual requirement of the memory having to end at
not a multiple of 2M.
> But the “Node 0 Normal” zone, judging from (start_pfn, start_pfn+spanned) spans 100000000-f18000000.

Awesome, I'll set up a vm with that flavor to see if I can reproduce
this, or at least reproduce the problematic zone setup. Thanks!
