Title:
  [Dell Latitude 3150] Suspend / Hibernate will toggle Wifi / BT off /
  on with 14.04.2

Status in linux-lts-utopic package in Ubuntu:
  Confirmed

Bug description:
  CID: 201412-16319 Dell Latitude 3150

  Running hibernate or suspend will turn the Wireless network and
  Bluetooth off on the first time, and turn it on on the second time,
  however it can alway be re-enabled with the wireless hotkey.

  Steps:
  1. Install 14.04.2 + update
  2. Run hibernate with "sudo pm-hibernate"
  3. Wake it up.
  4. Hibernate it again.
  5. Wake it up

  Expected result:
  * Wireless and Bluetooth should be working all the time.

  Actual result:
  * They got disabled on the first, third, fifth... cycle

  You can replace hiberate here in the steps with suspend, and will get
  the same result.
