https://bugzilla.kernel.org/show_bug.cgi?id=211807 Bug ID: 211807 Summary: [drm:drm_dp_mst_dpcd_read] *ERROR* mstb 000000004e6288dd port 3: DPCD read on addr 0x60 for 1 bytes NAKed Product: Drivers Version: 2.5 Kernel Version: 5.10.16 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: low Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: kernelbugs@xxxxxxxxxxxxxxxxxxxxxxx Regression: No In my logs, I see the following error: [drm:drm_dp_mst_dpcd_read] *ERROR* mstb 000000004e6288dd port 3: DPCD read on addr 0x60 for 1 bytes NAKed It has not caused any detected issues, but I guess that if the kernel complains this loudy, it is good to report it. This is on a laptop with a Ryzen Pro 4750U APU. I custom-build the kernel, so do not hesitate to request changing some config options to investigate. -- You may reply to this email to add a comment.
