New Catalina install takes 15 minutes to boot.

Hi all, I've been asking around in the discord chat however I haven't been able to get anyone to help me yet with this new issue.

I decided to make the switch from a distro to vanilla recently after doing a Powermac G5 conversion to ATX hardware, and i'm going to be honest, i've been having issues at basically every step but have been able to get past them on my own (Until now).

While booting from USB, the boot process seems to get stuck on "IOConsoleUsers: gIOScreenLockstate 3" for about 15 minutes, until which it gets to the Apple loading screen and boots up just fine. I know that this is a graphics related issue, however the troubleshooting portion of the guide (Side note, CSM will NOT stay off, instead it errors at boot and turns back on) nor extensive googling have gotten me to a solution, and without one this project might be dead for me.

Any help is SUPER appreciated! I can upload any files from my bootstick if needed.
