As Michel asks me here https://bugs.freedesktop.org/show_bug.cgi?id=82050#add_comment > (In reply to comment #65) > Keep in mind that revert broke 32bit complitely, lot of corruption :) >I haven't been able to reproduce that. If you still can, please file a bug for >it, as there's nothing preventing the kernel from using GTT instead of VRAM when >the latter is full. 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 :)
