<pre>Hi,
I just had the exact same problem. Actually twice in a row it seems.
The second one the pc recovered. It took some time to accept CTRL-ALT-F1, after
log in, top shows some activity, and finally I could CTRL-ALT-F7 back to the
GUI.
dmesg shows:
[ 1475.042636] [drm] stuck on render ring
[ 1475.042639] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[ 1475.042639] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 1475.042639] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 1475.042639] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 1475.042640] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
I have the error file, I'll try to attach it.
Btw, this is on a DELL Latitude E5430, running Ubuntu 14.04 Trusty Tahr
(AMD64), with unity 3D. Recently I installed latest XBMC 13.0 Gotham (don't
know if that's related, but there is v-sync tear regression that appears in
XBMC 13 - but I don't have the TearFree option in xorg.conf afaics).
