Radeon deadlock with Flash + VDPAU

1) Enable VDPAU support in flash player [1]
2) Visit web pages such as [2] (in that page the hang happens
   when the AD has been played and the actual video should start).

At this point the flash player hangs (plugin-container process with firefox),
and there's no way to resume it other than killing the parent process.

It seems like a deadlock, see the attached backtrace; not sure if this has
something in common with <a class="bz_bug_link 
          bz_status_RESOLVED  bz_closed"
   title="RESOLVED NOTOURBUG - Freeze caused by 'winsys/radeon: remove cs_queue_empty' commit"
   href="show_bug.cgi?id=70123">Bug 70123</a>.
This is when using mesa 10.1 (4a86465) in Ubuntu 14.04.
