https://bugzilla.kernel.org/show_bug.cgi?id=217892 Bug ID: 217892 Summary: [amdgpu]: system freezes when trying to turn back on monitor Product: Drivers Version: 2.5 Hardware: All OS: Linux Status: NEW Severity: normal Priority: P3 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: mmk+bugs@xxxxxxxxxxxx Regression: No Hi, My setup is a dual monitor 4K/144Hz with running sway on it. Both monitors are connected via DP to a Advanced Micro Devices, Inc. [AMD/ATI] Navi 31 [Radeon RX 7900 XT/7900 XTX]. Usually if i don't change monitor settings everything works as expected. The monitors do also wake up flawlessly after system idling. However, sometimes i turn off the second monitor (for example for playing games). For that i made a shortcut in sway which looks like this. > bindsym $mod+Shift+F12 output DP-2 toggle Now, turning the monitor of works as expected. However, turning it back on i encounter following erros/problems: Main Workspace (Desktop) freezes, second monitor tries to get turned on. (The monitor led goes up) After some time (couple of seconds, around 10-15sec) the main desktop works again, the second screen goes off again. At that point i usually have to reboot the system to get the second monitor back. In dmesg is see following entries: [ 8623.325357] [drm] enabling link 1 failed: 15 [ 8623.382238] [drm] REG_WAIT timeout 10us * 5000 tries - enc32_stream_encoder_dp_unblank line:348 [ 8623.437493] [drm] REG_WAIT timeout 10us * 5000 tries - enc32_stream_encoder_dp_unblank line:357 [ 8638.435963] [drm:amdgpu_dm_atomic_check] *ERROR* [CRTC:81:crtc-3] hw_done or flip_done timed out This is also something which can be reproduces quite easily. However sometimes it works almost without problems. (in that case, the monitor comes back but the desktop on the main monitor looks distorted/corruped - maximizing a application fixes that) This also seems to be a regression. With kernel 6.2 and 6.3 this worked as expected. I'm using following kernel: Linux x2 6.5.2-gentoo #1 SMP PREEMPT_DYNAMIC Sat Sep 9 00:29:42 CEST 2023 x86_64 AMD Ryzen 9 7950X3D 16-Core Processor AuthenticAMD GNU/Linux As soon as there is a linux-6.6 kernel available in gentoo i'll try that one too. -- You may reply to this email to add a comment.
