Chris Rainey, to advise, given this is Lauchpad (downstream reporting
system) it's impossible to mark it a duplicate of an freedesktop.org
(upstream reporting system) report, or any other reporting system. Also,
this is not considered being tracked at bugzilla, as this hasn't been
confirmed to be related.

Despite that, this report (downstream) is still pending
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1503731/comments/12
. Given your belief there is a commonality to an upstream report, it
would help to provide evidence of it by confirming the regression commit
noted in the upstream report is indeed the same for your hardware.

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

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Ever since I first installed 15.04 back in April/May on my new DELL
  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.

  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).

  WORKAROUND: Use kernel boot parameter:
  intel_idle.max_cstate=1

  I have gained _significant_ improvements in reliability / stability by
  using 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.
