The current leading cause of such errors, assuming an up-to-date libdrm/etc, is multithreading in the application. Nouveau does not handle this well. I have a branch which tries to address this: <a href="https://github.com/imirkin/mesa/commits/locking">https://github.com/imirkin/mesa/commits/locking</a> However it's not quite there yet (although it's a good part of the way there), and needs a rethink on some of the core mechanisms used. Unfortunately the libdrm_nouveau api is really not well-suited to multithreading, kicks can end up resulting implicitly from all kinds of seemingly innocuous actions.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
