In top, if you do 'H' (to show threads) and 'g Xorg', you might see an Xorg thread stuck on a DMA fence; WAIT might be "dmafenc" or something else in the kernel's drm code. My amd64 desktop freezes in the same way, but not so quickly; I often use Xorg for hours without a freeze. I often run Xfce with emacs, firefox, sylpheed, and xfce4-terminal (as I am doing now). When the screen does freeze, I typically ssh in and reboot(8). My amd64 desktop has the same cpu as you (Ryzen 5 3400G), but I have 16G RAM (you have 48G), and I use the 3400G's integrated graphics (you seem to use discrete graphics). My screen is 1920x1080 (yours is 1920x1200). My board never ran 6.6, but started with 6.6-current; later snapshots fixed some amdgpu problems. I suspect a problem in the kernel, but have never found a cause. The symptom is a dma fence (in the kernel) that never gets signalled, so Xorg or an X client is stuck at the fence. Sometimes, the dmesg gets a message like, "ring gfx timeout". I have also seen graphical glitches, like windows blinking (I use xfwm4's compositor; they blink more often in bsd.sp than bsd.mp), and glitches in supertuxkart. Multiple people have reported X freezing on amdgpu or radeondrm to this bugs list in recent months. --George
