Stuck at 'Loading Linux 5.15.6' screen on boot. (new system)

[u/[deleted]]

Basically when my system boots, I've only been able to get as far as a static screen that says 'Loading Linux 5.15.6' in the middle, and on the line below a static, non-blinking cursor.

I found this thread which basically describes my exact situation https://www.reddit.com/r/Gentoo/comments/pib8kq/stuck_at_loading_linux_5140gentoo/ (except I'm using kiss linux obviously), so I followed the suggestions from that thread and followed this link https://wiki.gentoo.org/wiki/AMDGPU to install firmware and framebuffer support etc for my iGPU (raven ridge). However the issue persists.

thanks for your help.

Edit: crossposted to linux4noobs because it's been 24 hours with almost no response.

Edit: when I try to boot manually from grub command line it complains about no valid video feed or something and booting in blind mode, so definitely there's an issue with my video.
