One of them from a few days ago where the GPU managed to recover (if we can call that "recover" it was barely functional and had to reset via Ctrl+Alt+Supr). Another from today I just repro again and was totally unable to recover, screen flashed several times as if it tried to soft reset more than once (I'm not certain that's what happened), still could do Ctrl+Alt+Supr to reset. I've been thinking these few days this bug MIGHT be related (causing): <a class="bz_bug_link bz_status_REOPENED " title="REOPENED - [radeonsi] Graphics lockup while playing tf2" href="show_bug.cgi?id=93649">https://bugs.freedesktop.org/show_bug.cgi?id=93649</a> If the game for just one frame randomly presents an invalid setup for one measly small object, it would hang Radeon 7770s but it would work fine for everybody else including these users in Windows (seriously, in my own program I could not visually tell what was missing, it was some small object in a cubemap render used for reflections) and nobody would notice. If you have a suspect on where I should look (i.e. you have Mesa code that SHOULD be catching this incorrect setup but isn't; I can analyze why it's not catching the error) I can insert a few printfs or hook gdb. As a graphics programmer I have my pride to keep.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
