[Bug 106859] [snb] Graphic corruptions and GPU hang

--- Comment #19 from Laurent Bonnaud <L.Bonnaud at laposte.net> ---
I also tried to run firefox with intel_sanitize_gpu:

$ intel_sanitize_gpu /usr/local/firefox-64/firefox --no-remote
INTEL-SANITIZE-GPU: error: missed drm fd 3
INTEL-SANITIZE-GPU: error: missed drm fd 45
[...]
INTEL-SANITIZE-GPU: error: missed drm fd 36
[...]

It kind of works, but it looses my saved session (hundreds of tabs), therefore
I will not be able to do real tests with intel_sanitize_gpu.

Other problems are:
 - the hamburger menu does not pop up
 - the default "new tab" page is not displayed properly and when I tried to
interact with it I got a complete freeze.  After rebooting I found this in the
logs:
