unable to resume from suspend

Describe the bug When i suspend my system and try to resume again by hitting a key on the keyboard, the computer turns on (power supply clicks, fans turn on) but the screen stays black.

I have to turn it off hard by holding the power button for several seconds, to start it clean.

I'm able to reproduce it reliably with the provided steps to reproduce.

When RAM is not full, i don't have this issue.

There are also mentions of amdgpu. Maybe it could be related to that?

In any case, this looks like a kernel/driver issue and not caused by nixos itself.

This is the log from the time i suspended:

no amdgpu or kernel errors

To Reproduce

With this i'm able to reproduce it reliably:

close every program except terminal
disable swap

sudo swapoff -a

fill 99.9% of RAM

nix run nixpkgs.stress-ng -c stress-ng --vm-bytes $(awk '/MemAvailable/{printf "%d\n", $2 * 0.999;}' < /proc/meminfo)k --vm-keep -m 1

suspend the system. it can take some time until the system actually turns off
try to resume. the system does power on, but i see a black screen. at that point, kernel errors are written to journal
you have to hard shutdown the system by holding the power button
start the system and check journal for kernel errors

Expected behavior Suspend and resume without issues

Additional context I'm using the Pantheon desktop and have an AMD RX 480.
