Solus 4, issue has been present since an AMD card (RX580 4GB) was installed in this machine in july and has happened nine times.
The machine, asleep, wakes up, fans and LEDs come on, but there is either no video signal out or there is a signal showing only a frozen screen of a clock when the machine fell asleep. No keyboard input has an effect.
The machine still responds to pings over the network. DVI or DP interface makes no difference.
Radeon RX 580 Series (POLARIS10 DRM 3.32.0 5.2.13-126.current LLVM 8.0.1) v: 4.5 Mesa 19.1.6 on Z170-HD3 mainboard, i7 6700 CPU.

Happened to me too on 5.3.4-arch1-1-ARCH after wake from suspend.
Seems to me the same as https://bugzilla.kernel.org/show_bug.cgi?id=204241 - which is resolved already - give those patches a try.
The OOPS following the resume failure is a side issue and should be handled separatly.
Thanks for the replies. Yes, looks like a dupe; I'll try to apply the last patch attached as soon as I've read up on how patch works. You can close this I guess.
