You mention though somewhere that you also experience memory corruption issues after hibernat (assuming I've read the comments correctly). We are aware of memory corruptions issues due to i915.ko when hibernating, unfortunately no one has yet root-caused this. See e.g. https://bugs.freedesktop.org/show_bug.cgi?id=35648 Cheers, Daniel -- Daniel Vetter Mail: daniel@ffwll.ch Mobile: +41 (0)79 365 57 48
