GPU crash dumb i915 /sys/class/drm/card0/error

The screen just freezes for 10 sec when I am doing web navigation, or using
flash API on Chromium. I am using 4th gen Intel HD graphic 4000 with Intel(R)
Core(TM) i3-3110M CPU @ 2.40GHz.


Here is the output of Xorg -version :

X.Org X Server 1.15.1
Release Date: 2014-04-13
X Protocol Version 11, Revision 0
Build Operating System: Linux 3.14.0-4-ARCH x86_64 
Current Operating System: Linux lenovo 3.14.4-LENOVO #1 SMP PREEMPT Sat May 24
13:02:10 IDT 2014 x86_64

Build Date: 14 April 2014  08:39:09AM

NOTE : The i915 drm driver is built-in for this kernel, but i think i
encountered the same issue when it is build as a module.

And here is the crash log

May 29 04:30:46 lenovo kernel: [drm] GPU hangs can indicate a bug anywhere in
the entire gfx stack, including userspace.
May 29 04:30:46 lenovo kernel: [drm] Please file a _new_ bug report on
bugs.freedesktop.org against DRI -> DRM/Intel
May 29 04:30:46 lenovo kernel: [drm] drm/i915 developers can then reassign to
the right component if it's not a kernel issue.
