assertion in nouveau_pushbuf_data at ../nouveau/pushbuf.c:723

This happens all the time when I'm trying to load cnn.com in WebKit minibrowser. More details about the scenario can be found at https://bugs.webkit.org/show_bug.cgi?id=200437

There is either segfault or assertion failure everytime I load the site. Attaching a couple of core dumps to the bug.

this is probably a multithreading bug inside mesa. We are aware of the situation, just fixing it might take a while as it requires bigger rework. We are on it though. Just limited in time sadly.

Thanks for your response. Let me know if you need help with testing the fix with the WebKit scenarios.
