           Summary: drm/i915: regression in LONGTERM kernel gpu driver >
                    kernel 3.2.46
           Product: Drivers
           Version: 2.5
    Kernel Version: 3.2.51
          Hardware: x86-64
                OS: Linux
              Tree: Mainline
            Status: NEW

        Regression: No

Drivers in kernel versions 3.2.46...3.2.51 are corrupting video memory and
crashing GPU on 

00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960
Integrated Graphics Controller (rev 0c)
00:02.1 Display controller: Intel Corporation Mobile GM965/GL960 Integrated
Graphics Controller (rev 0c)

and

00:02.0 VGA compatible controller: Intel Corporation Mobile 915GM/GMS/910GML
Express Graphics Controller (rev 04)
00:02.1 Display controller: Intel Corporation Mobile 915GM/GMS/910GML Express
Graphics Controller (rev 04)

after some time intermittently with blank screen on GM965 and kernel stalls on
915GM, 

must be one of those changes:
