booting to a black screen.
 

so I have completed the book to the t I believe, but I am still getting a black screen at boot up. I checked the journal and the system appears to be booting but it has these errors:
yellow:

then I have the following in red :

then back to yellow:

then a few other red lines ..

a few of my system specs:
ryzen 5g (on board graphics disabled in bios.. )
amd rx6600 gpu
32 gb ram
system is on a 50 gb ssd

so far I have tried:
re compiling the kernel
and placing amd gpu drives.
any help would be appreciated !

my suspicions ...

1) make sure VGA support is in kernel and your card supports it, to see CONSOLE output

2) looks like your modules aren't loading. trying booting same kernel on a (rescue) disk that works, and copying those modules (from your initrd?) into /lib/modules, run depmod.

do those modules load? if not: you need modules that load to boot normally. perhaps copy modules from (somewhere) that do work.

(note: obviously copy some non-essential modules that won't bork your rescue disk so that it cannot boot. don't copy all modules unless you have multiple /lib/module/kern-foo/ and know how to boot between them)

Moin,

Seems to happen on an AMD CPU? if so, do you have avaliable all necessary firmware blobs?
