So, the first thing I would try is disabling msi.  I added a tuneable to
do so.  MSI has had a lot of testing on radeon.  I've been working on
nouveau for the last week, so I'll get back to looking at radeon soon.
I have found a couple of bugs that I need to fix while working on
nouveau that might effect radeon as well.
