I have a Zen 2, Zen 3+ and a Zen 4 system and they all work well very with various Linux distros (Arch, Fedora) and recent kernels.
It’s very likely that your bug is specific to early Ryzen CPUs/chipsets. A couple of folks on those reports mentioned their issues went away after a motherboard/BIOS upgrade. So I think you’ll be fine if you went for a more recent AMD CPU+mobo.
