BSoD: [TTM] radeon failed to fill cached pool (r:-12)!

If I use vdpau (both directly and via vdpau-va-driver), after that I watch some
videos, my laptop hangs while suspending (and this happens always, after that I
opened a certain number of videos).

I'm using 3.0 Mesa 10.6.0-devel (10.6.0~git20150318) on kernel
3.16.0-34-generic.
My radeon card is: 01:00.0 VGA compatible controller: Advanced Micro Devices,
Inc. [AMD/ATI] Madison [Mobility Radeon HD 5650]

While generally this just leads to a frozen system, with no output, once I got
a BSoD (really, on linux!??) as you can see in the attached picture, saying:

[TTM] radeon 0000:01:00.0: Failed to fill cached pool (r:-12)!

 :00:16.0: request_threaded_ir failed: irq = 43
                               returns -12
                             me async: error -12
