 Dear Maintainer, 
  
 since the upgrade to Linux kernel 6.16.3, suspend to RAM no longer works on 
 my 
 system. 
 With kernel 6.12.38 (previous version in testing) suspend still works as 
 expected, so this is a regression introduced between 6.12 and 6.16. 
  
 --- 
  
 Observed behavior (user perspective): 
 - When suspending (on timeout or via power button), the screen turns off as 
 expected. 
 - Mouse and keyboard LEDs flash a few times, then remain dark (I did not 
 observer those flashes on previous kernels, but I am unsure). 
 - Screens go dark as expected. 
 - The system power button LED stays permanently on (it should normally turn 
 off). 
 - The system never resumes from suspend. 
 - Only a hard power-off (long press on power button) allows restarting the 
 machine. 
  
 **Note:** Any unsaved work in RAM is lost due to the required hard reset. 
  
 Expected behavior: 
 - System should suspend and resume properly, like under kernel 6.12.38. 
  
 --- 
  
 Log excerpt (from `journalctl -b -1`): 
  
 Sep 10 07:33:02 computer-id kernel: amdgpu 0000:0b:00.0: amdgpu: MODE1 reset 
 Sep 10 07:33:02 computer-id kernel: amdgpu 0000:0b:00.0: amdgpu: GPU mode1 
 reset 
 Sep 10 07:33:02 computer-id kernel: amdgpu 0000:0b:00.0: amdgpu: GPU psp 
 mode1 
 reset 
 Sep 10 07:33:02 computer-id kernel: amdgpu 0000:0b:00.0: amdgpu: psp reg 
 (0x16061) wait timed out, mask: 8000ffff, read: ffffffff exp: 80000000 
  
  
 This strongly suggests the issue is in the amdgpu driver. 
  
 --- 
  
 Reproducibility: 
 - Always, 100% reproducible. 
  
 Hardware: 
 CPU: AMD Ryzen 5 3600 
 GPU: Radeon RX 5500 XT 
  
 Additional information: 
 - systemd was upgraded to 258~rc3-1 at the same time, but suspend works fine 
 when booting into kernel 6.12.38 with the new systemd. 
 - Logs from the failing suspend attempt (`journalctl -b -1`) are attached in 
 full. 
  
 Thank you for your work on the Debian kernel! 
  
 Best regards, 
  
 Marcel Jira
