Title:
  [Dell Latitude E5250] Unable to complete the hibernate stress test

Status in linux package in Ubuntu:
  New

Bug description:
  CID: 201407-15278 Dell Latitude E5250

  Steps:
  1. Install 14.04.3 + update (3.19.0-31)
  2. Install the certification suite
  3. Test it with hibernate 30 cycle stress test
  or run the following command for 30 times:
  fwts -q --stdout-summary -r ./hibernate_30_cycles s4 --s4-device-check --s4-device-check-delay 45 --s4-sleep-delay 120

  Expected result:
  * It can pass the 30 cycle hibernate stress test.

  Actual result:
  * System will freeze on some point, in the most recent test, it freeze on the 9th cycle.

  From the hibernate test log, some HIGH failures could be found in it (but hibernate works this time, sometimes it does not):
  High failures: 5
   s4: Failed to freeze user space processes.
   s4: Failed to freeze remaining non-user space processes.
   s4: Failed to freeze devices.
   s4: Failed to allocate memory for hibernate image.
   s4: Failed to restore hibernate image.
