I have an AMD Raven Ridge (-like) APU with a Radeon Vega 8 (V1605B) as one of my R4.1 systems to play around with.
As R4.1 moved to kernel branches higher than 5.4 I have started to experience random freezes and crashes.
I was not always able to retrieve logs, but in cases I did, amdgpu has been involved.
If new releases of stable-5.10 or latest become available in the repositories, I try them out with mostly similar results.
If I do not want the system to freeze/ crash I start it with a self-compiled stable-5.4 kernel, which runs just rock solid.
The nature of the issues are especially Xorg crashes and the whole system freezing. In the first case I was able to obtain some kernel buffer messages, in the latter I was not able to get any logs.

This most likely a driver/ kernel/ Xen issue, but as here is the most likely place to find people who run Xen on Raven Ridge, I just wanted to drop this here to ask whether this is a problem that other people Raven Ridge users are having, too.
