Yes, ryzen had issues in its early days:

I'm running Beowulf on a custom built ryzen 7 1800x system with a MSI
b350 gaming plus motherboard with a custom compiled 5.15.11 kernel
with no problems. While this is considered old hardware at end of
2021, I'm still amazed by how fast it is compared to what I was used
to for a long time before building this machine.
