Afteer using this PC for few days with AMD Vega 8 (integrated) as main GPU I
see no freezes at all. (before in 2021 it was freeze every 10-20 mins so I had
to use Nvidia as main GPU)
(works with and without listed above kernel boot option)

I use OpenSuse kernel 5.18.4-1-default (not going to update for some time,
because it works)

Maybe it just fixed for "my motherboard+CPU combination", my hardware:
Ryzen3 3200 CPU (Vega8 integrated) on A320M-DVS R4.0 motherboard. 
microcode: CPU: patch_level=0x08108109
microcode: Microcode Update Driver: v2.2.

Wayland and x11 works, with Nvidia as second GPU.
Wayland slowdown(to like 1-2FPS whole UI performance) once after few hours of
using, but it fixed just by switching to system-terminal(ctrl+alt+f1) and back,
nothing crash video apps and graphic keep working.

integrated GPU performance still goes down(in few hours, randomly in 2-6 hours
of PC use) and never go back, but its fine(since I have Nvidia second GPU for
complex graphic), Vega 8 performance go down only in "complex shaders" FPS drop
from 60 fullscreen(1080p) to 10-20 on complex raymarching shaders, but for
system UI (Wayland/x11 Gnome 42) this is not noticeable, and video play on
60fps as expected. (Sleep mode also works, not every time(because Nvidia) but
most of the time, same as when used Nvidia as main GPU)
