GPU crash dump
I have experienced a desktop freeze during few seconds. System messages relate
that to a GPU hang. In what follows, further information, and the GPU crash
dump.
* This situation was experienced under Kubuntu vivid (updated on the 22th,
december 2014), and compositor mode was enabled on the window manager kwin_x11.
(No problem encountered without the compositor mode)
* Linux version is 3.18.0-031800-generic #201412071935 SMP, from Ubuntu
repository
* The package used for xserver-xorg-video-intel is from
<a href="http://ppa.launchpad.net/xorg-edgers/ppa/ubuntu">http://ppa.launchpad.net/xorg-edgers/ppa/ubuntu</a>:
2:2.99.916+git20141215.99537089-0ubuntu0sarvatt
* system messages:
[ 3265.604584] [drm] stuck on render ring
[ 3265.606629] [drm] GPU HANG: ecode 0:0x002883e6, in kwin_x11 [3333], reason:
Ring hung, action: reset
[ 3265.606640] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 3265.606644] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 3265.606649] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 3265.606653] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
