More info: The secondary monitor lights up, but just shows a black screen with the mouse cursor, but the primary monitor does not. This makes me suspect that my primary monitor is the culprit. As before, the kernel freezes for about a minute or so in that state, and then recovers. The dmesg output is shorter this time: [Feb 3 19:20] [drm] perform_link_training_with_retries: Link training attempt 1 of 4 failed [ +0.407677] [drm] perform_link_training_with_retries: Link training attempt 2 of 4 failed [ +0.460615] [drm] perform_link_training_with_retries: Link training attempt 3 of 4 failed [ +0.420583] [drm] enabling link 0 failed: 15 [ +0.177390] [drm] perform_link_training_with_retries: Link training attempt 1 of 4 failed [ +0.060044] [drm] perform_link_training_with_retries: Link training attempt 2 of 4 failed [ +0.111304] [drm] perform_link_training_with_retries: Link training attempt 3 of 4 failed [ +0.159993] [drm] enabling link 0 failed: 15 [Feb 3 19:21] [drm] REG_WAIT timeout 10us * 3000 tries - dce110_stream_encoder_dp_blank line:955 There was no backtrace like last time. BTW, note that the kernel "thinks" that ~1 second passed, based on those timestamps, but in reality, it was about a minute. -- You may reply to this email to add a comment.
