Indeed, the backport of fa90035 is faulty (and there's another missing
mei driver commit as well).  Pali, please test this fix (the top two
patches) and advise whether that fixes the problem:

Title:
  Regression in mei_me.ko for 3.13.0-51

Status in linux package in Ubuntu:

Status in linux source package in Trusty:
  In Progress

Bug description:
  After upgrading linux-image-3.13.0-49-generic to linux-
  image-3.13.0-51-generic I started getting this error message in dmesg:

  [ 6.352555] mei_me 0000:00:16.0: irq 47 for MSI/MSI-X
  [ 6.355708] mei_me 0000:00:16.0: version message write failed: ret = -5
  [ 6.355712] mei_me 0000:00:16.0: hbm_start failed ret = -5
  [ 6.355714] mei_me 0000:00:16.0: reset failed
  [ 6.355716] mei_me 0000:00:16.0: link layer initialization failed.
  [ 6.355717] mei_me 0000:00:16.0: init hw failure.
  [ 6.355880] mei_me 0000:00:16.0: initialization failed.

  Downgrading back to linux-image-3.13.0-49-generic fixed this problem.
  So this is regression for version 3.13.0-51.
