We already know about this backtrace. It's a possible sideffect of a overloaded/dying gpu, but unrelated to the bug at hand. > In this special case the gpu was successfully reset and continued normally. > > Any other ideas? Not at the moment, unfortunately. Can you please report a bug against libva with a small summary of all the things we've already discussed here? Also please add a error_state with my patches applied. And don't forget to put me on cc and post the bug # here in this thread.
