I am on Kernel
Linux 3.15.0-999-generic #201404260253 SMP Sat Apr 26 06:54:32 UTC 2014 x86_64
x86_64 x86_64 GNU/Linux
This bug happened the first time today during regular use having chromium,
terminals and vim open (using the dwm window manager). The XServer seemed to
hang and was not responsive for a few seconds. Soon after it started to react
properly again and the dmesg output suggested to file a new bug report (it may
be a duplicate of <a class="bz_bug_link
bz_status_RESOLVED bz_closed"
title="RESOLVED INVALID - [drm] stuck on blitter ring"
href="show_bug.cgi?id=75991">bug 75991</a> however).
Please find the dmesg output, the /sys/class/drm/card0/error output and the
Xorg.0.log attached.</pre>
