Sometimes after my machine resumes from suspend my display stays off with no signal, and USB keyboard (Num lock) and mouse doesn't react.
This time I managed to SSH into the machine and gather some logs after it failed resuming.
I have experienced this with different kernels and under different Linux operating systems, like Debian and Gentoo, but it is not happening often enough for me to sense a pattern.
I will attach log files to the best of my abilities according to: https://amdgpu-install.readthedocs.io/en/latest/install-bugrep.html

Can confirm this problem on
Suspend & resume work flawlessly on
Can you bisect?
Is there a Fedora workflow for bisecting?
Also, do I need to take care of any GPU firmware or is it just the kernel?

Don't worry about the firmware, just the kernel is fine. Here's a bisect howto tailored to fedora:
The kernel-package.py script is broken.
I'll build kernels directly.
Git bisect says approximately 13 steps are required between v4.20 and v5.0.
Will report back in ~14 days when that's done (bug manifests only after some uptime).
Bisection turns out to be harder than anticipated because there is another bug that makes the system freeze on suspend (not reported yet).
Anyways, this seems to be a duplicate of https://bugs.freedesktop.org/show_bug.cgi?id=111729#c7
Potential fix (and kernel Bugzilla bug): https://bugzilla.kernel.org/show_bug.cgi?id=204241
