Everytime the screen blanks the following error will be displayed in the journalctl log: kernel: amdgpu 0000:0b:00.0: [drm] REG_WAIT timeout 1us * 100 tries - dcn32_program_compbuf_size line:138 When the screen resumes (Not from Standby only when resuming from screen blanking)the following error appears: kernel: amdgpu 0000:0b:00.0: [drm] REG_WAIT timeout 1us * 100 tries - dcn32_program_compbuf_size line:139 I have bisected the Kernel versions and until 6.11.3 the bug doesn't happen, first with 6.11.4 the bug appears. I have no Problems with crashes or freezes, it is only this message in the logs. At the moment i use kernel 6.13.1 but ia have tested kernel 6.14.0-rc1 where the bug also appears. I use a PowerColor Radeon RX 7900 XT Hellhound OC for display. If other Informations are needed i would happily provide it. -- You may reply to this email to add a comment.
