So I:

  1. Went to www.buildwithchrome.com and fooled around for a minute.
  2. Then everything hung.

Found this in dmesg after killing Chrome.

  * WebGL is enabled in Chrome, I'm guessing this has something to do with it.
  * I'm using UXA because SNA was too unstable in Google Maps, would always hang.

Versions:

  Arch Linux 3.13.0-1-mainline #1 SMP PREEMPT Mon Jan 20 12:44:30 CET 2014 x86_64 GNU/Linux

  xorg-server 1.15.0-5
  xf86-video-intel 2.99.907-2

Well, here you go anyway:

[ 3448.838407] [drm] stuck on render ring
[ 3448.838410] [drm] stuck on blitter ring
[ 3448.838412] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[ 3448.838413] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[ 3448.838414] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[ 3448.838414] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[ 3448.838415] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.

Hope this helps you.
