Question: Shouldn't the evaluation and fix be targeted at Rawhide
first, and then see about "backporting" demonstrated fixes to Fedora
21? For all we know now, these could be significant new features. Or
alternatively a lot of work may have to be repeated if it turns out
the problems don't occur, or the solutions are radically different, if
Wayland is being used instead of X11.

Further, the sample size is two models. Identifying a common source
problem probably means looking at more hardware.
