Well, confirmed at last. The bug was still present in the "original" 3.9.0.rc5
with partial RV's patch. It failed with a single error after more than 30h
uptime. So, the patch does not resolve the issue.

In the meanwhile, I've update my work PC to Ubuntu 13.04 (kernel
3.8.0-19-generic). The interesting thing is that it failed today with the
classic message:

"[drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU hung"

I say it is interesting because it never failed with previous kernel versions
(which failed in my home PC). Furthermore, as it is up and running much more
time than my home desktop, it would be easy to test kernels or patches and
accumulate uptime.

So, feel free to share any patch you would like to test.
