I did get the "flip_done timed out" log messages 6-7 minutes after the system booted at 17:20 on July 13: Jul 13 17:26:38 rpi4a.WalkerStreet.info kernel: [drm:drm_atomic_helper_wait_for_flip_done [drm_kms_helper]] *ERROR* [CRTC:66:crtc-3] flip_done timed out Jul 13 17:26:38 rpi4a.WalkerStreet.info kernel: [drm:drm_crtc_commit_wait [drm]] *ERROR* flip_done timed out Jul 13 17:26:48 rpi4a.WalkerStreet.info kernel: [drm:drm_crtc_commit_wait [drm]] *ERROR* flip_done timed out Jul 13 17:26:58 rpi4a.WalkerStreet.info kernel: [drm:drm_crtc_commit_wait [drm]] *ERROR* flip_done timed out Jul 13 17:27:08 rpi4a.WalkerStreet.info kernel: [drm:drm_crtc_commit_wait [drm]] *ERROR* flip_done timed out -- You are receiving this mail because: You are on the CC list for the bug.
