What is the impact of this error? > Also, have you verified this issue with latest drm-tip? I've only experienced it a few times, it happens cca once a month, and always it's docked, driving 2 external screens and the eDP display. When I leave it like this for a while and DPMS kicks in, there's a small chance that when I later try to log back in, one of the displays won't come back online and then I usually have a few seconds until the machine freezes completely. Yesterday I managed a "sync" before that happened, so this dmesg snippet is all I have now. I turned DPMS off as a workaround but I'll try to get to testing drm-tip sooner or later.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
