OK... so I tried three runs of the stress-ng memory test (that has been used successfully on every other system we certify for 16.04) and so far, two of three runs have resulted in the system locking up and a bunch of stack trace data dumped to console.

In both cases, I had to power cycle the system to reboot it into a usable state.

All three attempts were 16.04 w/ hwe-edge (4.10) deployed by MAAS.

System info:

stress-ng:
  Installed: 0.07.21-1~ppa
(We keep an updated version of stress-ng in the cert PPA, it's not modified from Colin's code)

I've attached logs (kernel and syslog, other info) in a tarball to this.
