By the logs I can see that both GPUs have one CRTC and one plane enabled so maybe the mux is not working and both GPUs are driving/trying to drive the same panel - can you disable the AMD GPU in BIOS or blacklist the module and test it? - can you apply this patch <a href="https://bugs.freedesktop.org/attachment.cgi?id=142181">https://bugs.freedesktop.org/attachment.cgi?id=142181</a> on top of drm-tip and test it?(with AMD GPU still disabled) - can you apply this patch <a href="https://bugs.freedesktop.org/attachment.cgi?id=142181">https://bugs.freedesktop.org/attachment.cgi?id=142181</a> on top of drm-tip + <a href="https://patchwork.freedesktop.org/series/50843/">https://patchwork.freedesktop.org/series/50843/</a> and test it?(with AMD GPU still disabled) Thanks</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>
