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
