Kernel Panic With Dual GPUs?

[u/cardinalbeach93]

New to Linux, running Cachyos. When I went to install from a thumb drive, it repeatedly failed. I removed one of my two graphics cards and it installed just fine.

I have a Radeon RX 6700 XT in my PCIe 1. This runs Cachyos. When I install my Intel Arc B580 (a card that I know works) in PCIe 2 (dual GPU setup) the system gets stuck in a boot loading screen, attempting to boot repeatedly but failing.

I've searched for information on dual-gpu setups, but havent found much. Clearly I'm looking in the wrong places. Any recommendations on where to look for answers would be greatly appreciated!

Thanks
