Radeon makes Flash player with VDPAU enabled hang at vlVdpDecoderDestroy → flush → radeon_drm_ws_queue_cs

Description

Created attachment 98951 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 Bug 70123. This is when using mesa 10.1 (4a86465f) in Ubuntu 14.04.

[1] echo -e "EnableLinuxHWVideoDecode = 1\nOverrideGPUValidation = 1" >> /etc/adobe/mms.cfg [2] http://video.corriere.it/i-ragazzi-anni-90-come-eravamo/9fd1a13c-d9b5-11e3-8b8a-dcb35a431922
