I can also reproduce the bug using the new Google Maps (easiest way to do so seems to be zooming in/out). However it occurs for me even after I disable semaphores:
(after that):
[614445.590357] [drm:i915_hangcheck_elapsed] *ERROR* stuck on render ring
[614445.590468] [drm:i915_set_reset_status] *ERROR* render ring hung inside bo (0x5268000 ctx 10) at 0x5268210
this is ubuntu 13.04 with 2.21.6-0ubuntu4 intel driver, but kernel 3.11.1.
