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.

[1] echo -e "EnableLinuxHWVideoDecode = 1\nOverrideGPUValidation = 1" >>
/etc/adobe/mms.cfg

Ah, this is not happening when using intel, then I suppose this is not an issue
of the flash blob.

It's not happening with Intel because the drivers don't support VDPAU.

Yes, of course... But I meant using the VDPAU support thought va_gl.
Also if VDPAU is not using mesa, in that case, I guess that if the problem
would be in flash, then it would have hanged even when using va_gl, isn't it?
:o
