Bug report looks good, but mailing your maintainer won't scale. Please
file at bugs.freedesktop.org against dri -> drm/intel. You can pretty
much ditch all the additional information, save for maybe an lspci -nn
attachment.

Also, retesting on latest 3.6-rc3 kernels would be rather interesting,
we've fixed a few things that /might/ apply to your issue.

Yours, Daniel

> [X.] Other notes, patches, fixes, workarounds:
> It is imperative that you include any further debugging information
> from http://www.kernel.org/doc/Documentation/ using the mainline
> kernel. Failure to provide the information from the documentation
> mentioned for the driver or subsystem your reporting a bug in, may
> likely result in negative unintended consequences. In addition, please
> be 100% certain you have included all relevant comment information not
> included in the Bug Description and a kernel developer should review.
> They are some of the busiest people in the Linux space. They do not
> need to dive through downstream bug reports to find something that
> should have been provided when the bug was first filed. If you are
> unsure about anything asked for, or intend on not following this
> format, please do not file a report. Instead, continue to ask
> questions in Launchpad, and of the Ubuntu community, until all issues
> are cleared up.
