Error log

I actually didn't know what happen, but as I open dmesg it shows this, so I
just submit this.

System is Archlinux 64-bit, Kernel 3.18 (as shown in the error log).

The dmesg tells 2 error, but only produce 1 error log, for a reason I just
don't know. Quoting dmesg:

[182837.319770] [drm] GPU HANG: ecode 0:0x00ababab, in systemd-logind [248],
reason: Ring hung, action: reset
[182837.319772] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[182837.319774] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[182837.319775] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[182837.319776] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[182837.319777] [drm] GPU crash dump saved to /sys/class/drm/card0/error
