Other people seem to be booting fine with this GPU. There is no blacklisting in /etc/modeprobe.d/ going on. I installed mesa, xf86-video-amdgpu, vulkan-radeon (not the git experimental) _common_interrupt: 10.55 No irq handler for vector CPU - AMD Ryzen 5 5600X CPU Cooler - ID-Cooling SE-224-XT ARGB Black GPU- XFX QICK 319 AMD Radeon RX 6700XT Hard Drive - MSI Spatium M370 1TB NVMe M. _common_interrupt: 9.55 No irq handler for vector _common_interrupt: 8.55 No irq handler for vector _common_interrupt: 7.55 No irq handler for vector _common_interrupt: 6.55 No irq handler for vector _common_interrupt: 5.55 No irq handler for vector _common_interrupt: 4.55 No irq handler for vector _common_interrupt: 3.55 No irq handler for vector _common_interrupt: 2.55 No irq handler for vector _common_interrupt: 1.55 No irq handler for vector

While booting I get the following output before it: Clock: GPU / Memory, Boost Clock: Up to 2581 MHz/16.0 Gbps, Game Clock: Up to 2424 MHz/16.0 Gbps Key Specification, AMD Radeon RX 6700 XT Graphics, 12GB 192-bit GDDR6 16 Gbps, 3 x DisplayPort, 1 x HDMI, 267 x 120 x 50 mm (without bracket)
Key Features, AMD RDNA 2 Architecture, 7nm GPU, PCI Express 4.0 Support, AMD FreeSync Technology, Radeon Image Sharpening, Radeon. 6700xt drivers

I checked my fstab just to make sure it has the correct UUID and it does. I had to use the 'nomodeset' Kernel parameter to boot the arch iso for installation. I just did a fresh install on my desktop after dropping a new AMD 6700XT into it and I think my GPU has something to do with it not booting since arch ran fine with my nvidia 1030.
