I have a 3700x system (but running Windows) at home.
Check with the motherboard vendor first? My board¹ has received three or four updates since I got it (which .. is an entirely different can of worms and doesn't exactly inspire confidence yet). At least they do seem to propagate things "quickly" I guess..
That's as well my understanding of the situation => does anybody have more infos?
I was really about to upgrade from an i7-8700 to a Ryzen 3700X but after reading this I froze and now I feel totally insecure... .
