output of dmesg captured as journalctl -b-1 after a     crash

I have tried to provide the info requested by Intel and recommended by
Fedora[1].  Kudos to the Fedora folks for providing very detailed
instructions!

If some information is missing please let me know.


1 System environment
════════════════════

  – chipset: HD 4000 with Intel i7 Ivy Bridge system architecture:
  – x86_64 xf86-video-intel: 2.99.91 (2.99.917) xserver: 1.16.3 (1.17.1)
  – mesa: 10.4.3 (10.4.5) libdrm: 2.4.59 (2.4.59) kernel version:
  – 3.18.7-200.fc21.x86_64 (3.18.6-1-ARCH) Linux distribution: Fedora 21
  – (Archlinux) Machine or mobo model: Thinkpad W530 Display connector:
  – laptop screen

  I conduct the test below in Fedora.  I normally use Arch.  The problem
  is present in both distros.


2 Reproduce steps. Probability if not 100% reproducible
═══════════════════════════════════════════════════════

  1. Download gputest from http://www.geeks3d.com/gputest/
  2. Run start_furmark_windowed_1024x640.sh.  Put it in full screen if
     you like.
  3. On my system the computer crashes and reboots typically within 10
     minutes.  The reboot is as if power was cut and returned.  Like if
     the CPU was overheating (which it is not).  IOW: The systemctl
     shutdown logs are not displayed.


3 Additional info
═════════════════

  I experience reboots crashing on my Thinkpad W530 with HD4000 whenever
  the iGPU is exposed to moderate load, e.g. playing a simple video game
  (Shadowrun and Mark of the Ninja are two examples).  This happens on
  my main distro: Arch and on Fedora.  This only happens when I employ
  the Intel iGPU.  It happens irrespective of whether Nvidia Optimus in
  enabled.

  Note: This is seemingly *not* a hardware issue!  I can run mprime cpu
  load indefinitely on the system without a crash.  The temperature
  never goes above 90 degrees when I run any test (and I had the fan
  replaced within the last three months).  My brother who also has a
  Thinkpad W530 experiences the same issue on Debian.

  Importantly: the computer is completely stable on Windows 7, where I
  have stress tested the system with the same procedure as below for 6-8
  hours (latest Intel drivers, Nvidia Optimus disabled).


  I have tested on Fedora 21 and Archlinux.  My brother, who also has a
  W530, has tested on Debian Sid.

  The tests are conducted on a clean Fedora 21 image ‘cause it’s better
  for debugging.

  • Xorg.0.log: for some reason not present.
  • xorg.conf: default setup.
  • the last batch buffer: it shows nothing interesting before the
    reboot.  Is there a way to record is persistently?
  • I’m trying to get a “kdump” of the kernel when it crashes as
    described here[2]
