i915_error_state after the hang

Bug description:

System hang when starting OpenGL java applications.

System environment: 
-- chipset: Integrated Graphics Chipset: Intel(R) Ivybridge Mobile (GT2)
-- system architecture: 32-bit
-- xf86-video-intel: 2.20.15
-- xserver: 1.12.3
-- mesa: 9.0.1
-- libdrm: 2.4.40
-- kernel: 3.6.6-porteus
-- Linux distribution: Porteus 2.0 (pre-RC1)
-- Machine or mobo model: Intel ChiefRiver
-- Display connector: HDMI1

Reproducing steps:

I can reproduce this 100% of the time, on both the above-described hardware,
and an Ivybridge desktop system. I am running a proprietary JOGL-based
application. I do not get the hang with trivial apps like glxgears.

Additional info:

The current revision of Porteus is based on a graphic stack that is over a year
old. That is completely stable on this hardware, but anti-aliasing does not
work, so for the release, they built an updated version for me to try. That
version hangs the GPU.
