It's a long shot, but does https://lists.freedesktop.org/archives/mesa-dev/2016-August/127318= .html fix it?

I can confirm on R9 390, this patch stops the GPU page faults in dmesg log,= but I'm still getting major corruption when recording the screen in obs or ffmeg https://youtu.be/pFqhIGYLbDM
Revert this patch to fix VDPAU corruption: "radeonsi: increase performance for DRI PRIME offloading if 2nd GPU is= CIK or VI" 5ee3cac1380fec6971e9d25267589a586da0ecd8.

I reverted this, rebuilt mesa, ran the ffmpeg command, played it back, the first 4 seconds is corrupt in the same way as before, then it's fine. Rebuilt obs-studio, the window now shows an uncorrupted screen! REbuilt ffm= peg and no corruption.
I can also confirm that the pagefaults above are back with thi= s patch reversion.

This issue wasn't limited to mobile Bonaire. One interesting h= int from bug 97610 is that it works fine with the radeon kernel driver, so maybe it's related to addrlib or the amdgpu winsys. Anyway, fixed for now in Git master. Note that you need to start X with the fixed Mesa, because it affects glamor as well.

Since Marek mentioned in the commit message of the revert, that it's maybe = some tile configuration issue, I was wondering if Tom was correct in bug 97610, comment #1? Should I do the test= =E2=80=93 obviously with the revert undone =E2=80=93 with the tiling configurations copied from radeon (bug 97610, comment #2)? Or is th= is something else?
