Some error messages during boot/startup

[Swedish_newbie]

Can anyone please explain what this means? (see attached picture)
I installed the latest version of Debian (10) yesterday on a Dell Prestige 2900 server and these messages appear during server startup and it takes forever before I can log in.

I would like to try to fix the errors, if I know what they meant.
I don't know much about debian/linux so I am therefore grateful for all the help i can get to fix the errors, so that I can get a flawless and faster startup of the server.

Yes, this photo, thank you for correction.
I would try to install non-free packages for firm-wares for radeon: firmware-amd-graphics
