Looks correct to me on rv790.
I get nothing like the corruption in the screens, for me it's just the band at the bottom of the screen and it's not always there (but seems to be reliable first test after boot from power off).
I tested a couple of cycles with mesa reset just before this commit and couldn't see the problem. With mesa on this commit I can see it.
Kernel is drm-fixes.
