The very first line of the screen session shows how the test is being
run:

/usr/lib/plainbox-provider-checkbox/bin/memory_stress_ng

The machine is completely unresponsive. No ssh, no ping and the console
over ipmi is locked up. Hitting CTRL+C over the sol console does nothing
at all. This is after leaving the test running for 18+ hours where it
should only take around 1-3 hours tops to complete depending on the
machine. As you can see on the same machine running the same test on
14.04, the test took about an hour to complete with no lockup at the
end.

Title:
  memory_stress_ng failing for IBM Power S812LC(TN71-BP012) for 16.04

Status in linux package in Ubuntu:
  Triaged

Bug description:
  memory_stress_ng, as part of server certification is failing for IBM
  Power S812LC(TN71-BP012) in bare metal mode. Failing in this case is
  defined by the test locking up the server in an unrecoverable state
  which only a reboot will fix.

  I will be attaching screen and kern logs for the failures and a
  successful run on 14.04 on the same server.
