System hang at random moments even on headless servers (without any monitor or X server installed). Here some testimonies and kernels logs : https://bugs.archlinux.org/task/66991 No issue on 5.6.
Please attach your dmesg output and xorg log (if using X).
Created attachment 289711 [details] Log before a crash
And I don't have X (headless server) however I have a GPU (Ryzen 3200G with Vega chipset)
Also on Kernel 5.8-rc1
Ryzen 3 2200G, had multiple random freezes with debian kernel package "linux-image-5.8.0-2-amd64". Now I am back to "linux-image-5.7.0-2-amd64" which was working nicely. Other notable packages: firmware-amd-graphics 20200918-1 amd64-microcode 3.20191218.1
Running linux-image-5.9.0-1-amd64 for quite some time now and it looks stable. AFAIK this was the fix: https://lkml.org/lkml/2020/7/27/64
