RX5700 works but 5700XT does not

I have a PowerColor Red Devil RX5700. In Windows (Installed for this purpose), I flashed one of the BIOS to an RX5700XT. It booted fine in Windows, but in linux, it was stuck after the "clean /dev/<drive> ..." line appeared. When flipping the switch back to the 5700 BIOS, it boots perfectly. If you need me to provide any config files or anything else, tell me. How do I get the 5700XT bios to work? Thank you.

I figured it out. I had to put "iommu=soft" in grub. That fixed it and it works perfectly now.
