system death under oom - 3.7.9
...on't have any swap set up, but my understanding is that this is not
required. The full log is at: http://pastebin.com/YCYUXWvV. It was in
my messages, so I guess the system took a bit to die completely.
nouveau is somewhat implicated, as it is the first thing that hits an
allocation failure in nouveau_vm_create, and has a subsequent warn in
nouveau_mm_fini, but then there's a GPF in

0xffffffff811325b1 <+138>: e8 a0 60 56 00 callq
