I have had problems booting linux on an Asrock x570 Taichi Razer with a Ryzen 9 5900X. So far, Fedora is first distribution that would boot. Unfortunately, after its first updates, it no longer boots.
The boot problems I have had seem to be related to graphics. The motherboard shows no problems but the screen is blank.
This system has a ASUS GeForce GTX 750 Ti, which is UEFI compliant. Earlier (not UEFI compliant) graphics cards are not recognized.
This card can probably be initially booted by editing the kernel command line from the grub menu and adding nomodeset into the line that begins with ‘linux’.
Once booted then installing the nvidia drivers from the rpmfusion repo should fix the problem.
The rpmfusion repo can be enabled through the software app, then the drivers installed with a command line command sudo dnf install akmod-nvidia xorg-x11-drv-nvidia-cuda.
The nvidia driver does require that secure boot be disabled in bios or that you create a certificate and sign the modules as shown at the rpmfusion web site.

I will try this in the morning. Thanks for your input.
