This is a bug in the Intel Mesa driver. Unfortunately I have little hope
that it will be fixed soon: "This suggests that we're missing a flush
somewhere... but finding where is like finding a needle in all the
haystacks. :(" (https://bugs.freedesktop.org/show_bug.cgi?id=80568)

Anyways, as far as Ubuntu is concerned this seems to be the same as bug
1382673, bug 1385810 and bug 1394424.

Title:
  [GM965] GPU lockup running OpenGL applications on Dell Vostro 1510

Status in Mesa:
  Unknown
Status in xorg package in Ubuntu:
  New

Bug description:
  Hello, I'm suffering a GPU lockup problem with Ubuntu 14.10 64-bit on
  a Dell Vostro 1510 laptop with Intel graphics. The problem used to
  arise also with Ubuntu 14.04 and is always reproducible with glmark2
  on the LiveCD. Just to run the "ideas" benchmark of glmark2 to trigger
  the lockup in few seconds (glmark2 -b ideas). Other OpenGL
  applications also causes the lockup (e.g. FooBillard++, my self-made
  SDL applications). Memory test passed, BIOS at the latest version.
  Don't know if the following is a good point but I think that the
  problem is not caused by a failing hardware because it works fine on
  Windows. I tried with the latest Intel upstream kernel
  (http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-
  next/current/) and upstream X.org (https://launchpad.net/~xorg-
  edgers/+archive/ubuntu/ppa), no change.

  [Personal Notes]
  I'm new to Ubuntu's world, I hope I've done things right, if not please tell me and I will resend the report or supply more information. I've created the bug report with "ubuntu-bug xorg --save" from another machine via SSH while the sick machine was frozen. It seemed to me more logical than using ubuntu-bug directly when the system is working fine. I've collected other information via SSH during the same lockup: dmesg, Xorg.0.log, i915_error_state. The latter was added as attachment.
