have had a dual boot win/linux system running a Ryzen 7. initially had a few weird issues with Manjaro (not sure if Ryzen specific) but got them sorted out. Ubuntu Debian and CentOS all seemed to run okay out of the box. Still trying to decide which I want to keep long term but linux with AMD/Ryzen seemed to be in a pretty good state to me.
Congrats, hopped over from HN and liking what I have seen so far. Will definitely be checking this out a lot in the coming months!
