Bug#689268: linux-image-3.2.0-3-amd64: Intel HD 4000 (Ivy Bridge) graphics freeze

[Rafael Cunha de Almeida <rafael@kontesti.me>]

I had a similar issue as described in this bug. I recently installed debian
wheezy on a thinkpad x230. As far as I know I use the same i915 module. I'm
using amd64 system and my cpu is "Intel(R) Core(TM) i5-3210M CPU @ 2.50GHz"

My system would freeze sometimes. When it did, I wasn't able to move the mouse,
write or anything. Trying to access through ssh didn't work either. My only
alternative was to forcebly restart the system. When the system was back up
there was no error log on /var/log/syslog, /var/log/dmesg or /var/log/kern.log.
It didn't write anything it wouldn't normally write other times on the moment of
the freeze.

I installed linux 3.7 from experimental and my computer has not frozen since.
