Getting "[amdgpu] trn=2 ACK should not assert!" when rebooting

Hi everyone,
I'm fairly new to Arch Linux, and I'm currently trying to utilize both of my GPUs (one is an Intel iGPU, the other is a rx 5700 xt as an external GPU connected via TBT3).
I'm trying to set the 5700xt as the default gpu. On the surface, everything seems fine. lspci and neofetch both return both GPUs, and all the recommended drivers for amdgpus are installed (mesa). But, I'm never able to use my 5700xt at all, there is no signal coming out.

Running dmesg returns

...
[71596.354884] amdgpu: trn=2 ACK should not assert! wait again !
[71596.364885] amdgpu: trn=2 ACK should not assert! wait again !
[71596.374944] amdgpu: trn=2 ACK should not assert! wait again !
[71596.384879] amdgpu: trn=2 ACK should not assert! wait again !
[71596.394701] amdgpu: trn=2 ACK should not assert! wait again !
[71596.408035] amdgpu: trn=2 ACK should not assert! wait again !
[71596.421360] amdgpu: trn=2 ACK should not assert! wait again !
[71596.434655] amdgpu: trn=2 ACK should not assert! wait again !
[71596.447981] amdgpu: trn=2 ACK should not assert! wait again !

repeated infinitely on the console. No progress can be made, and force-shutting my computer down is the only way to turn my computer off.

After a bit of searching, I found that I needed to also disable CSM in the BIOS, but that didn't help. I also have secure boot disabled.

I have the IT12 Mini PC, website here.
32 GB RAM, i9-12900H. The BIOS is also from American Megatrends.
I also have the Sonnet Breakaway Box 750 with the rx 5700 xt from PowerColor.

Any help would be appreciated!
