https://bugzilla.kernel.org/show_bug.cgi?id=209019 Bug ID: 209019 Summary: [drm:dpcd_set_source_specific_data [amdgpu]] *ERROR* Error in DP aux read transaction, not writing source specific data Product: Drivers Version: 2.5 Kernel Version: 5.8.1 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: rtmasura+kernel@xxxxxxxxxxx Regression: No In kernel 5.8.1 and kernel 5.8.2 I am having an issue with multiple displays. It's losing detection of one of my monitors and causing it to re-detect the monitors, and detects it, then loses it again, and re-detects, and so forth until it does eventually detect the monitor and the issue goes away for some time. It's random, I can't reproduce it at will. I have managed to trigger it: 1. By maximizing a window on a monitor that is not the one it loses connection to. 2. The screen graphical effect such as when xfce-screenshooter darkens the screen to capture a region Let me know if there's anything else I can provide. I think Arch Linux is currently at 5.8.3, so I'll do an upgrade. uname -a: Linux abiggun 5.8.2-arch1-1 #1 SMP PREEMPT Thu, 20 Aug 2020 20:45:00 +0000 x86_64 GNU/Linux dmesg: [21159.093638] [drm:dpcd_set_source_specific_data [amdgpu]] *ERROR* Error in DP aux read transaction, not writing source specific data [21159.542494] [drm] amdgpu_dm_irq_schedule_work FAILED src 1 [21169.281470] [drm:dpcd_set_source_specific_data [amdgpu]] *ERROR* Error in DP aux read transaction, not writing source specific data [21169.712677] [drm] amdgpu_dm_irq_schedule_work FAILED src 1 [21179.389388] [drm:dpcd_set_source_specific_data [amdgpu]] *ERROR* Error in DP aux read transaction, not writing source specific data [21179.832841] [drm] amdgpu_dm_irq_schedule_work FAILED src 1 [21180.189786] [drm:dm_restore_drm_connector_state [amdgpu]] *ERROR* Restoring old state failed with -12 [21193.108746] [drm:dm_restore_drm_connector_state [amdgpu]] *ERROR* Restoring old state failed with -12 [21203.108238] [drm:dpcd_set_source_specific_data [amdgpu]] *ERROR* Error in DP aux read transaction, not writing source specific data [21203.563296] [drm] amdgpu_dm_irq_schedule_work FAILED src 1 [21231.665363] [drm:dpcd_set_source_specific_data [amdgpu]] *ERROR* Error in DP aux read transaction, not writing source specific data [21232.103796] [drm] amdgpu_dm_irq_schedule_work FAILED src 1 [21232.201005] [drm:dc_link_detect_helper [amdgpu]] *ERROR* No EDID read.
