RX 7800 xt GPU - doesn't turn off on system shut down

[dreamLogic]

I bought a new graphics card and am using it fine with the latest default "bin" kernel. However when I shutdown, Gentoo seems to shutdown like normal but the GPU (+mobo, etc) actually stays on. I have to force a power off by holding the power button down.

I saw some other posts here and there on the internet about this card and it seems to boil down to the kernel?

Currently on break at work so I probably won't respond until later tonight (like 6 hours from now), but let me know what other info I should provide.
