[bug] Radeon 3900XT not switch to graphic mode on kernel 5.10

[Deucher, Alexander]

[AMD Public Use]

It looks like the driver is not able to access the firmware for some reason.  Please make sure it is available in your initrd or compiled into the kernel depending on your config.

Package linux-firmware-20201218-116.fc34.noarch is already installed.
Dependencies resolved.
Nothing to do.
Complete!

Looks like firmware is present. So I didn't understand why the kernel
cannot read firmware.
