Can't boot installer, waiting on ioproviderclass

I'm trying to boot to the installer on my amd-based build, but as the title says, I keep getting stuck at "waiting for ioproviderclass". I used the install image from amd-osx.com to make my usb, and I already tried the fix here: https://forum.amd-osx.com/viewtopic.php?t=2565. I tried swapping usb ports while booting, but that didn't help anything. I can't boot from a usb2 port, as I don't have one.
