--- Comment #6 from valtteri.rantala at intel.com ---
Reopened issue still exists.


Tested also Ben's branch

http://cgit.freedesktop.org/~bwidawsk/mesa/log/?h=halign_fast

That seem to help it a little
for Synmark multithread case it GPU hangs 1 out of 3

Later with the additional test causes a system hang.
Here are new dmesg.
[  167.712499] [drm] stuck on render ring
[  167.714151] [drm] GPU HANG: ecode 9:0:0x85dffffb, in synmark2 [3031],
reason:
 Ring hung, action: reset
[  167.714157] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[  167.714159] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[  167.714161] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[  167.714163] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
