On the 3rd try with a new iso, and on the media test on my new Ryzen computer, plymouth started for a little while, and then aborted, but with all the same errors as before.
So I decided to reboot and just click install and see what would happen.
( I used the latest Everything Boot Rawhide iso )
I now have a working Ryzen computer with Fedora Rawhide.

This is an ASUS motherboard with no wi-fi ( I have a wi-fi card to install later ). The video card is a used Power Color 5500XT ( bought in USA for around $ 129 USD plus tax ) Rawhide is on the primary NVMe drive. Cooler is the massive Noctua.
I purchased the Ryzen 3 1200AF from
* aaawave.com http://aaawave.com*
for around $ 77.95 USD ( free shipping ). No problems.
I spent a lot of money on the motherboard, having purchased it before the X550's were available. I am not pleased with the PCH fan-speed, but it is only 1600 to 2150 at idle in BIOS. That is with the PCH fan being new. Imagine what it will be like in a year or two. Ouch !
To be continued.
