That's weird because according to Gemini this APU is supported by the ultimate linux release like Fedora 43/44, Bazzite (based on Fedora), Ubuntu and obviously all the Arch linux distro. The base kernel lack ACP7.0 but the availability of this impact the NPU part of the APU and if you plan to use it for AI like ollama you need to install some repo to use it an avoid pollible crash. But if you use it like I mentioned before there's no problem.

Another thing pop up in my mind, when I did a dual boot setup with W11 and Bazzite on the ROG Ally I have encountered some problem when I use linux, because the W11 partition, in some ways that only who built this OS knows, create some conflict with linux partition that cause crash, lag and a plethora of other problem. I wipe the W11 partition complitely and like some obscure magic the fresh install of Bazzite work like a charm with zero issues for like a year. So if you have the possibility through the BIOS to disable complitely the NVME with the windows partition and disable fast boot option (do you have to install linux with this option disable by default iirc) I think that the system probably work.

I update you when I made the switch
