Thanks! Ok here's feedback already, I haven't had any issues with "random" desktop freezes since yesterday since I applied the patch <a href="https://patchwork.freedesktop.org/patch/335077/">https://patchwork.freedesktop.org/patch/335077/</a> So basically I can now use desktop for the most part without nodma globally enabled, I will report back if it turns out not to be the case. With all those 3 patches applied, Rocket League successfully launched 2 times out of 10, so I could say that 80% of time it will still provoke the SDMA type hang. Unfortunately this is the only game that I know that provokes the SDMA hang compared to ring_gfx hangs on Starcraft II and Rise of the Tomb Raider.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
