Title:
  S3 Failures on certain Dell Haswell systems with 3.11 and 3.13 Kernels

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Dell has reported that certain models of their Haswell-based systems
  have been having issues with S3, starting with the 3.11 kernels in
  13.10.

  Here are some data points for now:

  1) Doesn't happen on ubuntu or debian with 3.7
  2) Doesn't happen on 13.04 with stock 3.8 kernel
  3) Happens on stock kernel for 13.10
  4) Happens on 3.13-rc8
  5) Specific to Dell HSW HW.  Not happening on other OEM HSW HW from what has been reported.

  Business-Client machines (such as Optiplex, Latitiude, etc) seem to
  reproduce the issue, but, systems like the XPS 13 with Haswell do not.

  Some tests are being run on an Optiplex 9020 to try and narrow down
  what exactly might be wrong.
