Hi folks.
I bought myself a gift a new AMD 6900 XT graphics card to replace the
AMD Radeon VII.
But all joy was overshadowed that this video card did not working in Linux.
Output on the my boot screen was ended with message "fb0: switching to
amdgpudrmfb from EFI VGA" and videocard not switched to graphic mode.

I suppose the root of cause my problem here:

[    3.961326] amdgpu 0000:0b:00.0: Direct firmware load for
