Description
Created attachment 98951 Radeon deadlock with Flash + VDPAU
- Enable VDPAU support in flash player [1]
- 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 Bug 70123. This is when using mesa 10.1 (4a86465f) in Ubuntu 14.04.
