I updated to the latest packages in Ubuntu, and this bug still exists. 

Daniel, are you sure this is a problem in i965? dmesg seems to indicate i915:

[   70.826529] [drm] stuck on render ring
[   70.826536] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[   70.826538] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[   70.826538] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[   70.826539] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[   70.826540] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
