<pre>I frequently play Dota 2 ( <a href="http://dota2.com/">http://dota2.com/</a> ) on my machine. Recently Dota 2
had a significant update, which included some graphics improvements. Since
then, I experience frequent freezes ingame.
Every 5 to 10 minutes, the game will freeze up, for about 5 seconds, and then
most of the time continue on as before.
Looking at my logs, I found messages like this, associated with the freezes:
kernel: [ 976.678551] [drm] GPU HANG: ecode 8:0:0x85dfffdb, in GLRenderThread
[5482], reason: Hang on render ring, action: reset
kernel: [ 976.678552] [drm] GPU hangs can indicate a bug anywhere in the
entire gfx stack, including userspace.
kernel: [ 976.678553] [drm] Please file a _new_ bug report on
bugs.freedesktop.org against DRI -> DRM/Intel
kernel: [ 976.678553] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
kernel: [ 976.678553] [drm] The gpu crash dump is required to analyze gpu
hangs, so please always attach it.
kernel: [ 976.678553] [drm] GPU crash dump saved to /sys/class/drm/card0/error
kernel: [ 976.693084] drm/i915: Resetting chip after gpu hang
kernel: [ 984.688951] drm/i915: Resetting chip after gpu hang
kernel: [ 994.739240] kworker/dying (4978) used greatest stack depth: 12344
bytes left
kernel: [ 996.707763] drm/i915: Resetting chip after gpu hang
kernel: [ 1010.655648] drm/i915: Resetting chip after gpu hang
kernel: [ 1022.686415] drm/i915: Resetting chip after gpu hang
I was then at kernel 4.4.19. I've since tried 4.4.39, 4.9.0 and currently I'm
running drm-tip 8c3608fc86d03a4ed5082734f751c2dc85a13ecb.
Neither kernel upgrade helped.
I have a
$ cat /proc/cpuinfo | grep name
model name : Intel(R) Core(TM) i5-5675C CPU @ 3.10GHz
so the GPU is a Iris 6200.
I've upgraded my userspace driver to 169c74fa6c2cd9c28dd7bfacd9639cd245b8c8a8
that also didn't help.
Motherboard: Z97M-G43
Display connector: DVI
Distribution: Gentoo
Reverting to mesa 11.2.2 resolves the issue, I've tried several versions after
that, including a recent commit, ce7a045feeef8cad155f1c9aa07f166e146e3d00.</pre>
