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:
<a href="http://lists.freedesktop.org/archives/mesa-dev/2014-August/066746.html">http://lists.freedesktop.org/archives/mesa-dev/2014-August/066746.html</a>
For the mesa part, i already bisected that it starts at (might be same reason
as <a class="bz_bug_link
bz_status_NEW "
title="NEW - Sudden framerate drops in multiple games when compiling with -mtune=generic (as well with -mtune=pentium-mmx and older CPUs)"
href="show_bug.cgi?id=83436">bug 83436</a>, but let alone that one for now):
<a href="http://cgit.freedesktop.org/mesa/mesa/commit/?id=07c65b85eada8dd34019763b6e82ed4257a9b4a6">http://cgit.freedesktop.org/mesa/mesa/commit/?id=07c65b85eada8dd34019763b6e82ed4257a9b4a6</a>
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 :)</pre>
