(In reply to Andrey Grodzovsky from comment #4) > What happens if you disable GPU reset by loading the kernel with > amdgpu.gpu_recovery=0 ? Good point, I forgot to mention that I added `amdgpu.dc=0 amdgpu.gpu_recovery=1` in an attempt to work around this issue just before reproducing it again. So I can confirm that I could reproduce this issue both without any amdgpu kernel parameters and with the above two. I now did some more testing with kernel 5.3.2 and `amdgpu.gpu_recovery=0` (removing the `amdgpu.dc=0` too). Initially I could not trigger the bug, but I got it when letting the desktop environment (KDE) trigger its screensaver while Godot was running on the AMD GPU. Once I resumed from the screensaver, the GPU crashed (note: I did trigger suspend-to-RAM, the laptop was still powered). The dmesg output is attached. To compare, I did another test with kernel 5.1.20 (using `amdgpu.dc=0 amdgpu.gpu_recovery=1`), letting it go to sleep with Godot running on the AMD GPU, and it resumed without crashing. I also attach the dmesg output for comparison.
