PCIe passthrough is tricky, even though it ultimately manifests as a stack trace in the guest OS, it may be caused by the host OS or any hardware settings. Can you check if it works with another Linux distribution as the guest?

Sorry for the late reply, I've been quite busy this past days and i kinda forgot. Anyways I've managed to boot debian testing with the passtrough, so it isn't an host os error

@sairon sorry to mention you, you might have missed the issue

I did not, I just didn't have an opportunity to look into that - until now. I am able to reproduce the issue with this card too and confirm it really works on Debian-based distros (tested latest stable Debian and Ubuntu). However, it fails the same way on Arch Linux (both with 6.6 linux-lts and 6.10 linux), and when I applied Ubuntu's kernel config to HAOS build (with some minor modification that are required for successful boot), the problem persisted, so it's unclear to me yet why it works on Debian. There are still some more things to try, for example testing of other mainstream distributions, ideally those running the same minor kernel version (i.e. 6.6.y) without many patches. That way we could start "bisecting" the configuration to find what's needed to make it working.
