<pre>Running kernel 3.9.x (3.9.4 now), git mesa, git ati driver I had no issues with
these adjustments:
# cat /etc/environment
LIBGL_DRIVERS_PATH=/opt/xorg/lib/dri/
R600_DEBUG=nodma
and:
# git diff
diff --git a/src/gallium/winsys/radeon/drm/radeon_drm_winsys.c

No GPU hangs. No weird radeon related stuff in /var/log/messages.
I could even run bfgminer succesfully with tstellard's recent Cayman fixes for
llvm/OpenCL.
Bisecting got me nowhere. :-(
So what would be a next step?</pre>
