Thanks for the feedback, Emmanuel.
Adam: We don't have the check above in trusty, so you'll need to
resubmit including a backport of the above change. Please test as
thoroughly as you can with any Intel 3xxx or 7xxx hardware you've got
access to. If you'll point me at a build I can help test it as well (but
not until next week as I'm travelling atm).
Thanks,
Seth
