["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Chris Rainey, the next step is to fully commit bisect from kernel 3.16
to 3.19 in order to identify the last good kernel commit, followed
immediately by the first bad one. This will allow for a more expedited
analysis of the root cause of your issue. Could you please do this
following https://wiki.ubuntu.com/Kernel/KernelBisection ?

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

Thank you for your understanding.

Title:
  8086:0f31 Ubuntu 15.04-15.10 freezes totally

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Behavior:

  Ever since I first installed 15.04 back in April/May on my new DELL
  Inspiron 3646:

  Handle 0x0001, DMI type 1, 27 bytes
  System Information
          Manufacturer: Dell Inc.
          Product Name: Inspiron 3646

  I have experienced frequent(daily/every-other-day)complete
  lockups(cannot even switch to console(Alt-F1,F2,etc.).

  I have determined that the issue is related to the 'i915' driver in
  relation to my GPU:

  00:02.0 VGA compatible controller: Intel Corporation Atom Processor
  Z36xxx/Z37xxx Series Graphics & Display (rev 0e)

  on SoC:

  Handle 0x0004, DMI type 4, 42 bytes
  Processor Information
          Socket Designation: CPU 1
          Type: Central Processor
          Family: Atom
          Manufacturer: Intel(R) Corporation
          Version: Intel(R) Pentium(R) CPU  J2900  @ 2.41GHz
          

  I have gained _significant_ improvements in reliability / stability by
  using various flags / parameters in the i915 module:

  /etc/modprobe.d/i915.conf:

  options i915 semaphores=1

  and / or

  /etc/default/grub:

  GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_pstate=disable"

  and / or

  /usr/share/X11/xorg.conf.d/20-intel.conf:

  Section "Device"
     Identifier "Intel Graphics"
     Driver "intel"
     Option "TearFree" "1"
  EndSection

  and / or

  Disable "Intel Virtualization Technologies" in the BIOS.

  I'm currently using:  intel-linux-graphics-
  installer_1.2.0-0intel1_amd64.deb

  from:  https://01.org/linuxgraphics

  with similar results(maybe a little better than the stock i915 stack
  in 15.04).
