[Bug 1386695] Re: [3.16.0-23] Resume from suspend/hibernation, GPU lock - possible regression


It seems I'm unable to narrow down the commit.

I can assure (because I have tested this twice) the last bad kernel is

3.17.0-rc7-utopic (http://kernel.ubuntu.com/~kernel-

and the first good one

3.17.0-utopic (http://kernel.ubuntu.com/~kernel-

I did all the steps to spot the good commit, but I couldn't.

Here is the bisect log from git

Built and tested all the commits, but didn't work. 

Any ideas ?

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

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

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




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


  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 


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