Linux PCI issue

[Nirallan]

Hello all,

After updating BIOS to 3279 (latest version) for the motherboard B650E-F,  I'm no longer able to boot into, or install any Linux distro. The issue seems to stem from it not being able to initialize my 4080S card. The error I get is "Failed to register device, this PCI I/O region assigned to your NVIDIA device is invalid".

I have found the parameters "pci=nocrs pci=realloc" to be somewhat of a workaround, but none that I can safely rely on. It's worth mentioning that prior to the BIOS update, my NixOS setup worked perfectly.

Any pointers, or suggestions?

Bios: 3205

MB: X670E-F

GPU: RX 7900XT 

After upgrading to 3205, Linux is not bootable anymore(black screen) with enabled ReBAR option.

Asus, have you run it at least once with any Linux distro before releasing the BIOS?
