[Mesa-dev] [Libva] vaPutSurface never returns

[Christian König]

Questions for VDPAU should probably go to either the Mesa list or the 
VDPAU list, libva is completely unrelated to this.

Well is it possible that you just locked up the GPU? Please take a look 
at /sys/kernel/debug/dri/0/radeon_fence_info and dmesg.

Regards,
Christian.
