+++ Split separate issue out of Bug #77207.  Actual reporter is Benjamin Baumgärtner <bb@knacknuss.de> +++

I upgraded my Ubuntu trusty to today's state of the xorg-edgers PPA:

xserver-xorg-core	2:1.15.1-0ubuntu2
xserver-xorg-video-intel	2:2.99.911+git20140507.18416b51-0ubuntu0ricotz~trusty
libegl1-mesa:amd64	10.3.0~git20140514.8a9f5ecd-0ubuntu0sarvatt~trusty
libgl1-mesa-dri:amd64	10.3.0~git20140514.8a9f5ecd-0ubuntu0sarvatt~trusty

$ glxinfo | grep Mesa
client glx vendor string: Mesa Project and SGI
OpenGL renderer string: Mesa DRI Intel(R) Ivybridge Desktop 
OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.3.0-devel
OpenGL version string: 3.0 Mesa 10.3.0-devel

I'm still experiencing problems. Garbage screen output disappeared, but the screen is stuck for 5-20 secs every 1-3 minutes.

The kernel ring buffer says:
[  333.738942] [drm] stuck on render ring
[  333.738951] [drm] GPU crash dump saved to /sys/class/drm/card0/error

So I'm still having trouble, even with xserver 1.15.1 and a recent mesa version.

Benjamin

Please test a new version of Mesa (12 or 13) and mark as REOPENED
if you can reproduce and RESOLVED/* if you cannot reproduce.

If you can reproduce, please capture and upload an apitrace (https://github.com/apitrace/apitrace) so that we can easily reproduce as well.

I don't actually see in the report what the user did to trigger the hang.

Comment 2 Benjamin Baumgärtner 2016-11-03 19:56:12 UTC

I don't have the affected hardware in use anymore (bug report is 2+ years old!), hence I can neither test nor reproduce the issue with a recent version.
