@jsalisbury

thanks for offering assistance and willing to help.

I've finished the process of reverse bisecting and I have spotted some
good(bad) commits.

With the **priceless** help of @apw in IRC I have learned the correct
procedure of reverse bisecting (it was a real learning curve!)

Here is the new log

# first bad commit: [5838ae610ff36777b8fce6f353c2417980c1a1fa] drm/nv50/disp: fix dpms regression on certain boards

Now I have to test the commits beginning by the first bad (good) and
building-installing-testing the kernel(s).

But is it possible that in a case, 2 or 3 commits combined would be needed, in order to fix a problem?
 
The only commits relevant with my problem, as I can understand, are 3 (drm/nouveau/fbcon  /nv50 /nv50/disp). 

But maybe I need to combine them all together in order to fix the resume
problem, I'm not sure.

Title:
  [3.16.0-23] Resume from suspend/hibernation, GPU lock - possible
  regression

Status in The Linux Kernel:
  Confirmed
Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  I'm testing the new development branch (Vivid Vervet), which currently
  has the Utopic kernel 3.16.0-23-generic installed (proposed
  repositories are enabled).

  This problem might be a regression, and it has been reported

  upstream:

  https://bugs.freedesktop.org/show_bug.cgi?id=81136

  Problem:

  When I try to resume from hibernation the screen hangs and the GPU is
  locked. It cannot load the graphics properly.

  Testing:

  Unloading or blacklisting the nouveau driver and perform the following
  test, seems to indicate that  the problem is nouveau:

  # echo platform > /sys/power/disk
  # echo devices > /sys/power/pm_test
  # echo disk > /sys/power/state 

  Mainline:

  The problem seems to be fixed in latest stable mainline kernel, for now
  3.17.1-031701-generic (Utopic).
