Priority: medium Bug ID: 78641 Assignee: dri-devel@lists.freedesktop.org Summary: Radeon makes Flash player with VDPAU enabled hang at vlVdpDecoderDestroy → flush → radeon_drm_ws_queue_cs Severity: normal Classification: Unclassified OS: All Reporter: mail@3v1n0.net Hardware: Other Status: NEW Version: 10.1 Component: Drivers/Gallium/r600 Product: Mesa

Created attachment 98951 --> https://bugs.freedesktop.org/attachment.cgi?id=98951&action=edit 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 (4a86465) in Ubuntu 14.04.
