This looks like random corruption again. It's probably a bogus 'struct page' that fails the move_freepages() pfn_valid() checks. I'm too lazy to go reproduce the likely stack trace (not sure why it didn't show up on your screen), but this could just be another symptom of the same issue that caused the TLB batching oops.
My money is on this being some kind of odd stack corruption, maybe interrupt-induced, but that's a total guess at this point.
