No lockups/crashes with your "radeonsi: Disable asynchronous DMA"-patch after 4
days.

I did some testing today with a 23 minute full screen flash video:

Mesa 10.3.2 with the patch: 10 playbacks of the video, no crashes/lockups.

I built and installed mesa 10.3.2 from debian same source package without the
patch:
Run 1: fifth playback of the video crashed.
Run 2: fourth playback of the video crashed.

I think no further testing of this patch is needed, indicates something wrong
with the DMA code?
