Title:
  [Dell Inspiron 3558] System can't pass the suspend 30 cycles stress
  test

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  CID: 201411-16162 Dell Insprion 3558

  This system can pass a single suspend test but can't pass the 30 cycles suspend stress test. It will hang somewhere in the process (not sure if it's resuming or suspending). 
  With:
  * screen off
  * keyboard not responding
  * does not respond to power button, you can't wake it up with that

  However If you hold the power button for a while, you will hear that
  the HDD stop spinning.

  Steps:
  1. Install 14.04.2 + updates (3.16.0-46)
  2. Run the 30 cycle S3 stress test with checkbox

  Expected result:
  * System works fine after this stress test

  Actual result:
  * System hung during testing.

  Reproduce rate: > 80%
