--- Comment #10 from hadack@gmx.de --- I have the gpu lockups too on an 7750 in different apps, for instance xonotic. I did a bisect and it led to this commit:
e8f9195e5fb34a45783d6491d2e0305a0b137439 is the first bad commit commit e8f9195e5fb34a45783d6491d2e0305a0b137439 Author: Axel Davy axel.davy@ens.fr Date: Thu Aug 15 12:47:58 2013 +0200
gallium, intel: Implements new __DRI_IMAGE_USE_LINEAR and PIPE_BIND_LINEAR flags to enforce no tiling.

And indeed reverting it seems to fix the lockups.
