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
Hi Marcel, the bug. Along though I have two questions: Can you please test the current version in unstable (6.16.5-1), is the problem solved there? If not: Can you bisect the upstream changes to isolate the commit which breaks the behaviour? (Do you need rough instructions on how to do it?) Regards, Salvatore
Hello Salvatore! Thank you very much for looking into this issue - I really appreciate your help. I have tested the kernel from unstable. My `uname -r` shows 6.16.5+deb14-amd64. Unfortunately, the suspend problem still persists: the system hangs exactly as described in my initial report. I am attaching the full kernel log from this boot session (`suspend-6.16.5.log`) and also the `dmesg` log (`dmesg-6.16.5.log`). Regarding bisection: I would prefer to avoid it, as I am not experienced in this procedure and would also need to resize my root partition to accommodate more kernels. I hope the attached logs contain the necessary information to help sort out this issue. Please let me know if you need any additional information. All the best Marcel Am Mi., 10.

Hi Salvatore, I encountered the same issue, and was able to bisect. I'm pasting the result below. Thank you for looking into this. Let me know if I should report it upstream instead. cheers, Niklas 165a69a87d6bde85cac2c051fa6da611ca4524f6 is the first bad commit commit 165a69a87d6bde85cac2c051fa6da611ca4524f6 (HEAD) Author: Lijo Lazar <lijo.lazar@amd.com> Date: Mon Jun 2 12:55:14 2025 +0530 drm/amdgpu: Add more checks to PSP mailbox [ Upstream commit 8345a71fc54b28e4d13a759c45ce2664d8540d28 ] Instead of checking the response flag, use status mask also to check against any unexpected failures like a device drop.

Just in case it is relevant, some info that I forgot to share yesterday: 1. my GPU is a Radeon RX 5700 2. dump of /sys/kernel/debug/dri/0/amdgpu_firmware_info 3. full boot log using kernel from bad commit 165a69a87d6bde85cac2c051fa6da611ca4524f6 I hope this helps :) cheers, Niklas
Hi Niklas,
Ok that is great you found the offending commit. Can you try if
applying 440cec4ca1c2 ("drm/amdgpu: Wait for bootloader after PSPv11
reset") fixes the issue?
Regards,
Salvatore
Hi Niklas,
("drm/amdgpu: Add a noverbose flag to psp_wait_for") changes. So
either test mainline at the commit and the previous comit to confirm
the fix, and if possible then still with a backported variant.
An attempt of it is attached here which should apply on top of
6.16.7-1.
Regards,
Salvatore
Hi Salvatore, (resending previous message, because I forgot to CC the bug tracker) Thanks, the patch is working for me. I've applied it on top of v6.16.7 (131e2001572b) from mainline. Is that what you meant? I already reproduced the bug previously on v6.16.7, now with the patch applied, it is fixed. Let me know if you want me to test it on top of any other commit as well. Regards, Niklas
Hi
In Debian we got the report in https://bugs.debian.org/1114806 that
suspend to RAM fails (amdgpu driver hang) and Niklas Cathor was both
able to bisect the issue down to 8345a71fc54b ("drm/amdgpu: Add more
checks to PSP mailbox") (which was backported to 6.12.2 as well).
There is an upstream report as well at
https://gitlab.freedesktop.org/drm/amd/-/issues/4531 matching the
issue and fixed by 440cec4ca1c2 ("drm/amdgpu: Wait for bootloader
after PSPv11 reset").
Unfortunately the commit does not apply cleanly to 6.16.y as well as
there were the changes around 9888f73679b7 ("drm/amdgpu: Add a
noverbose flag to psp_wait_for").
Attached patch backports the commit due to this context changes,
assuming it is not desirable to pick as well 9888f73679b7.
Does that looks good? If yes, can you please consider picking it up or
the next 6.16.y stable series as well?
Regards,
Salvatore
Hi Greg, [note fixing up my typo for the Debian bug, sorry about that] Ah good, yes that should be equally fine (I missed the pending revert). Thanks a lot! Regards, Salvatore
