Bug description:
  A system being certified hangs hard when a VGA monitor is plugged in.
  The machine has a built-in DP MST bridge, but the driver has no
  support for MST. Upstream recently added a patch to add support for
  it, and it improves the situation that there's no hang anymore.
  Monitor still stays blank but that'll need another SRU once a patch
  for it is available.
