Not sure if this is related, but I swapped out the 1660 for a GTX 1050 Ti. The system ran fine since my last post (10/29/2019) until today: There was a short freeze (1-2 secs) from which the x server recovered with the following journal:

apart from the different GPU, the system is unchanged.
kaputt0nsqv: yours looks like a regular gnome bug of overqueueing frames. Try setting
in your system environment to work around it.
The rest of you: you all seem to be running 3rd gen Ryzen, since this seems to only happen while (mostly) idle, maybe somthing wrong with pcie power management, try setting kernel parameters
and check if that helps with the situation.
I also have the same problem, where my screen suddenly starts freezing and only mouse pointer works, while the rest of my applications that require GPU starts lagging. I’m using a Ryzen 3600 on a MSI x570, with a RTX 2070 SUPER. I have tried applying @generix’s proposed solutions, setting pcie_asm=off didn’t work – so i’m trying if processor.max_cstate=1 will help. Any other suggestions?
striffly, looks you already found the correct thread, didn’t look at your hw specs.
Would be nice if the thread starter could edit the thread title to reflect that Ryzen 3rd gen systems are affected by this.
Did any of you have positive/negative results with limiting cstates, i.e. kernel parameter processor.max_cstate=1 ?
MaxFramesAllowed was for a different issue.
On a another thread about a different issue on the same Ryzen platform, users reported that was fixed by a recently released bios update. Did you check if a bios update is available for your mainboard?
It’s definitely the combination that triggers this bug
Ryzen 3rd gen CPU
ASUS x570 + B450 mainboards
Nvidia Turing GPU
Anyone not falling into that category? Otherwise my guess would be a bios bug since so far only one mainboard vendor seems affected.
striffly, looking at the ASUS manual for their x570/B450 mainboards, running a single graphics card in any but the first slot (next to the cpu) is an unsupported configuration.
The slots are all for gpus but have to be populated in a specific order depending on number of gpus/Ryzen gen.
