TTY broken since Linux 6.1.0-xanmod1 with nvidia driver and efi (EFIFB)

[mskpluk]

Since upgrading to Linux 6.1.0-xanmod1, I have been unable to access tty. The last kernel in which tty functioned properly for me was Linux 6.0.12-xanmod1. It appears that the problem may be related to changes made in the upstream kernel:

There is further discussion about these changes and the associated bug at the following link:

Previously, the xanmod kernel was immune to this issue, but it has surfaced in version 6.1.0. Adding "nosimplefb=1" to "/etc/default/grub" has not helped to resolve the issue, nor has the patch from the following link:

https://github.com/NVIDIA/open-gpu-kernel-modules/issues/341#issuecomment-1367591000

Bug seems affecting both; users of open gpu kernel modules, and closed source.

Any ideas or suggestions for how to fix this issue?
