Title:
  [Dell Inspiron 5758] Unable to finish 30 cycle suspend stress test
  with fwts on Intel GPU

Status in linux-lts-vivid package in Ubuntu:
  Expired

Bug description:
  CID: 201501-16351 Dell Inspiron 5758

  When running with the integrated GPU (power-saving profile) on this
  I+N hybrid system.

  It will freeze on resume when testing with 30 cycles suspend test.

  But it works with the performance profile (NVIDIA GPU).

  Command:
  fwts -q --stdout-summary -r /home/ubuntu/.cache/plainbox/sessions
  /pbox-u2qsvl1w.session/CHECKBOX_DATA/suspend_30_cycles --s3-device-check
  --s3-device-check-delay 45 --s3-sleep-delay 30 s3

  Steps:
  1. Install 14.04.3 + update (3.19.0-33) + nvidia proprietary driver (346.96)
  2. Install fwts
  3. Install plainbox and canonical-certification-client from ppa:checkbox-dev
  4. Run plainbox run -i '2013.com.canonical.certification::power-management/suspend_30_cycles'
  (or you can run it with the fwts command mentioned above 30 times for the test)

  Expected result:
  * Everything works after s3 stress test.

  Actual result:
  * System stuck when resume from s3. I can't ssh into it, and CapsLock LED is not responding, but the magic key works (Ctrl + Alt + PrtScn + b)

  I tried to suspend it from the system menu, and wake it up with the
  power button to clarify this is not an issue to fwts, however, I can't
  successfully wake it up every time when running with the integrated
  GPU.

  fwts version 15.09.00-0ubuntu1~t
