I have a brand new install of Manjaro on a new HP 5z-ef2000 laptop with AMD Ryzen 5 5500U and Radeon Graphics. Suspend (using any method, such as close laptop lid, press power button, and systemctl) results in a completely black screen (appears black and off), but the laptop appears to still be running (e.g., fan stays on). There is no button combination that returns to a viewable screen. And the white light that indicates power remains on (whereas on other laptops I have, this light “bounces” on/off during suspend).
This problem seems to be common with Ryzen components on Linux computers. I have tried to solve it following some prior efforts (though with different distros and CPUs). Here are a few good ones: Arch; Ubuntu; Ubuntu/Arch; and general. I tried all of those on both PopOS (Ubuntu) and Manjaro (again – new computer, so no problem switching) – both run 5.15 kernel, .8 and .7 respectivey.
I also tried the suggestion on the ArchWiki Ryzen page about freezes. Well, just the one with the boot parameter processor.max_cstate=1, as my BIOS did not have an option for “Power Idle Control” or the like.
Lastly, I tried the 5.16 experimental kernel. It does change the behavior somewhat; the screen doesn’t go full dark (“black off”), but instead switches periodically between “black on” and a frozen home screen.
Here are the laptop’s specs from inxi:

I am currently switching everything to hibernate instead of suspend, but that only works intermittently for some reason – maybe because I also needed it to lock the screen upon wake.
But it would be awesome if there were an actual solution.
