 So i can reproduce it today too on 32bit (64bit is not affected, at least not
by corruption) drm-next-3.18 kernel, 3.17.rc7, current mesa git and reverted
this:

 http://lists.freedesktop.org/archives/mesa-dev/2014-August/066746.html

 For the mesa part, i already bisected that it starts at (might be same reason
as bug 83436, but let alone that one for now):


http://cgit.freedesktop.org/mesa/mesa/commit/?id=07c65b85eada8dd34019763b6e82ed4257a9b4a6

 For the kernel part not bisected yet, but it is somewhere in between 3.16 and
3.17-rc1, so hopefully i will bisect that maybe today :)
