Looks like rd.qubes.hide_all_usb is what's causing it to crash. When I remove 
it, it boots fine with the graphical splash and passphrase prompt. Another AMD 
Ryzen user mentioned having the same problem a while back. Something about 
AMD's IOMMU grouping of USB controllers, or something.

I'm planning on installing kernel-latest and I'll test it again when I do.
