Laptop does not go to sleep since last big update

About two weeks ago there was a huge update (like 500+ packages). Since than, the laptop does not go to sleep (S3). It seems to be an amdgpu issue. I fist thought, it might be a kernel issue but it happens with 5.10 LTS, 5.15 LTS, 5.16 and 5.17rc7. At least 5.10 and 5.15 did work before.

It did also not work when I disabled S3 and tried to use s2idle

I’m a big fan of AMD but the amdgpu driver is just the worst thing ever.

Any idea how to fix this? Maybe it’s the xf86-video-amdgpu? Or the firmware?

Edit: Downgrading xf86-video-amdgpu does NOT help

Edit 2: Using older Firmware files does also not help.
Additionally the system won’t shutdown properly after one failed attempt to go to sleep (happens always not just with the old firmware)

It seems, it actually is the kernel. I re-tried 5.10 and now suspend works again.

I have a similar issue but with hibernate that used to work fine…

I believe that I’m also experiencing this problem on my 5600XT
