Live cd's have problems booting with amd 3700x cpu and MSI x 570 a pro mother board

i had problems installing fedora on a new pc and  wanted to share what happened.
i filed a bugzilla report  https://bugzilla.redhat.com/show_bug.cgi?id=1740334

using gtx 1660 ti video card fails on fedora 29
using gtx 1050 ti works on fedora 29
using fedora 30 fails with both gtx 1050 ti and gtx 1660 ti video cards
mother board is msi x 570 a pro. cpu is amd 3700x  with bios update from 7-3-2019

fedora 30 kde spin live cd would not boot and showed systemd fail messages and then hung in both cases.

after switching to a gtx 1050 ti video card i was able to boot the fedora 29 kde spin and install it

did a dnf system-upgrade download 
and then a dnf system upgrade reboot to upgrade to fedora 30

system runs fine now with gtx 1050 ti video card after the upgrade to fedora 30
