[16931.086359] [drm] GPU HANG: ecode 9:0:0xfed7fffe, in Xorg [1392], reason: Hang on rcs, action: reset [16931.086388] drm/i915: Resetting chip after gpu hang [16931.788779] [drm:gen8_reset_engines [i915]] *ERROR* rcs: reset request timeout [16931.788826] [drm:i915_reset [i915]] *ERROR* Failed to reset chip: -5 So that looks like the DMC firmware fail, and then the GPU died. Unfortunately I can't find the appropriate bug for it right now. To (hopefully) fix that one would need the following patch: <a href="https://patchwork.freedesktop.org/series/33022/">https://patchwork.freedesktop.org/series/33022/</a> And get the KBL DMC 1.04 firmware from: <a href="https://github.com/anushasr/linux-firmware.git">https://github.com/anushasr/linux-firmware.git</a> Doesn't look like this is the problem for the other people here though.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
