   Dear Maintainer,   
   I wanted to report on a bug I'm facing on a fresh Debian 13.1 deployment, that   
   seems to be related to amdgpu driver.   
      
   The machine is an AMD Ryzen 5 7430U based laptop, that I'm running in a setup:   
   single external display over USB-C + internal display.   
   The issue is, switching windows between internal and external display, causes   
   the internal display to freeze at random.   
   Despite the screen freeze, windows seem to function underneath, I can blindly   
   do stuff and hear the results (eg. play on a video).   
      
   In dmesg I can see the following when freeze happens:   
   [ 2035.829247] amdgpu 0000:03:00.0: [drm] Mode Validation Warning: Unknown   
   Status failed validation.   
   [ 2035.844206] amdgpu 0000:03:00.0: [drm] Mode Validation Warning: Unknown   
   Status failed validation.   
   [ 2045.984304] amdgpu 0000:03:00.0: [drm] *ERROR* [CRTC:73:crtc-0] flip_done   
   timed out   
      
   Based on the online research, and the messages appearing as above, it leads me   
   to believe the issue might be amdgpu driver related.   
      
   What I know:   
   * The freeze happens on internal display only.   
   * The freeze is recoverable, disconnecting external display and plugging it   
   back resolves the issue.   
   * The freeze occurs randomly, yet I am suspicious that it is related to system   
   load.   
   * Before freeze, sometimes I can observe green compresion-like artifacts when   
   watching videos on YouTube.   
   * Running cpu stress test + watching a video will result in "flip_done timed   
   out" messages being shown in dmesg frequently, yet I was not been able to   
   intentionally make the screen freeze. The system can recover from these.   
   * The issue seems to occur often during watching YouTube videos (hw. accell.   
   decoding), yet, not allways.   
      
   What I've tried:   
   * Built upstream Linux Kernel 6.18.0-RC5. The issue seems much less frequent,   
   yet, it is still present. It is a difference between days and hours. Possibly   
   related to e5ae8d1eb08a3e27fff4ae264af4c8056d908639("drm/xe: Increase global   
   invalidation timeout to 1000us").   
      
   I am willing to provide more logs and test stuff if desired.   
      
   Thanks,   
   Mateusz
