Bug#687442: Success with linux-image-3.2.0-4.drm-amd64_3.2.35-3~jcristau.1_amd64.deb

[Ingo <ingo.steiner@gmx.net>]

I now tested Julien's kernel
(http://people.debian.org/~jcristau/wheezy-drm34/linux-image-3.2.0-4.drm-amd64_3.2.35-3~jcristau.1_amd64.deb)
with
DRM/KMS subsystem backported from 3.4, thoroughly. For 12 days it ran
absolutely smoothly without any freezes!

I did stress it in many ways, but did not observe any glitches. So this
kernel fixes bug #692234 and merged bugs 689268, ... for me.

My hardware in short form:

Ivy Bridge i5-3570k with
HD4000 graphics (no external cards), display connected to Display-Port
Intel DH77EB MoBo

All standard Wheezy-kernels up to 3.2.35 exhibited regular hard freezes
- sometimes more than once a day with power consumption some 30 watts up.

Juliens kernel for sure is an excellent alternative to using vanilla 3.4
kernel which also does the job. If Julien's fix/patches is ported to
Wheezy's kernel, please drop a short note here, so I can switch back to
standard Wheezy-kernel without beeing scared for my hardware.
