Vitaly, the next step is to fully reverse commit bisect from kernel 3.16
to 4.1-rc1 in order to identify the last bad commit, followed
immediately by the first good one. Once this commit has been identified,
then it may be reviewed as a candidate for backporting into your
release. Could you please do this following
https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F
?

Please note, finding adjacent kernel versions is not fully commit
bisecting.

Thank you for your understanding.

Title:
  BUG: unable to handle kernel paging request at f80f0000 -
  nouveau_bo_wr32+0x27/0x30

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Freshly installed 14.04.1-Ubuntu Desktop. First-time installation, no
  legacy from prior versions.

  Hardware: Asus P4C800 Deluxe, latest BIOS 1021.005 08/04/2005

  Easily reproducible. Immediately after installing Ubuntu Desktop,
  started getting freezes in the GUI. Usually happens within a minute or
  so of using the GUI after boot-up. The system is unusable this way.

  I am willing to make the machine available for remote or local (in
  silicon valley) debugging.

  ADDITIONAL INFORMATION:
  Anecdotally, I noticed that if upon boot-up, I first launch the command-line console (CTL-ALT-F1), then switch back to the graphical console (CTL-ALT-F7), then I am able to use the GUI for a couple of hours through normal shutdown without kernel crash. I observed this all of the 3 or so times that I did CTL-ALT-F1 and CTL-ALT-F7. This make it seem like some sort of a reference-counting bug: if I run CTL-ALT-F1 at least once, then the problem doesn't happen.

  Here is the stack trace from syslog:
