Bug description:
  Upgraded to zesty about a week ago. Ran into this on latest kernel.
  (during high load, nothing in particular seems to cause it to happen).

  Did not happen with previous (4.10.0.14.16) kernel. Only after update
  to 4.10.0.15.17, has happened about 3 times since then (or other
  crashes), this is the one I could capture.

  kern.log entries below. Let me know if you need anything else from me.

  Thanks!
