Hello everyone, happy to be here !

I have a problem in my last gentoo install. I am stuck at the infamous loading initramfs. I install the last kernel (gentoo-sources) for my install but this problem persist since at least a week so i have try several kernel in 6.1.X and in 6.2.X i have even reinstall two times but it seems i am still unable to fix the problem.
I understand this is a framebuffer issue.
I only have enable

lessblonux1,

Welcome to Gentoo Forums !

Maybe you are missing framebuffer console support. Please check if this is enabled:

Thank you very much to help.
Unfortunately i already have it.

First of all: Please check if you really boot THIS kernel ... I see some (many?) problems in your kernel configuration:

lessblonux1,

Just for testing make AMDGPU a loable module.

I think what happens now, that amdgpufb is broken and gets selected before there is any console output.

@pietinger :

I have try to read and improve my kernel config into a fedora that probably why you see that.

I tought CONFIG_SMP was the option to disable Hyperthreading i was wrong it seems it was SMT and this option doesn't exist anymore ...

Yes i have a AMD notebook with CPU 5600H and Radeon 6600.
I select the firmware according to the wiki.

The android stuff was part of the options i forget to disable, i am learning the hard way ...

For the LSM i have read somewhere that they can work together, my plan was to try them one by one and if necessary/best together that's why i don't force anyone.
Agagin i learn something and i will try them one by one.

Security is indeed one of my goal to have a custom kernel that also why i enable config_expert to enforce the rnd_bits stuff like in the hardened kernel.

Thanks for the wiki page.

@NeddySeagoon

Before throwing my config away i try your idea and it seems to work partially ... i can boot untill dracut stop me because e2fsck has unsupported feature C12 so filesystems still has error ...

My question is what does that means if i want to have moduleless kernel ?

I haven't find anyone who has this e2fsck error in gentoo (but in Debian yes) see :

https://forums.debian.net/viewtopic.php?t=154055

I will try to use the latest e2fsprogs (v1.47) in testing and see what happend.

lessblonux1,

Can you fsck your root filesystem from the boot media?

The initrd build tools usually don't use the packages that they find on your system.
So that they have more control over the content, they usually build their own packages which bay be different versions to the ones you have installed.
Long story sort, you may need to coax the initrd build tool of your choice to use a newer ext2ftstools ... or even build your own initrd.

So ,i try to use fsck -c /dev/nvme0p2 (my root partitions) and he reports no errors even he claims filesystem was modified, and a reboot after nothing changed. I also try smartmontools but if i understand correctly this software doesn' t support nvme very well, and he reports ne errors anyway

Next as i planned, i try to reinstall with a livegui of gentoo but i was unable to have acces to a the graphic environment ( yes i have check the blake2 of my iso ).

So i find an old Fedora 32 live installer usb with an old e2fsprogs and recreate a partition table and reformat my nvme.
The installation after that was without problem untill the reboot ...

I install a kernel with amdgpu modules, then when i reboot no framebuffer problem this time but dracut could'nt find my root partition.

lessblonux1,

/etc/fstab cannot be used to mount the root filesystem as its located on the root filesystem which can't be read as its not mounted.
That's an infinite loop.

The way that is broken is by passing root= on the kernel command line. That allows the kernel or the initrd to find the root filesystem.
The problem is either in your initrd or in grub.cfg where the root= statement might be incorrect.

You say that root is at /dev/nvme0p2.

Boot to the grub menu. Highlight the entry you want to boot, then press 'e' for edit.
Find the the root= statement on the kernel command line.
Change it to read

First thanks to both of you for your help, i am really greatfull.

Yes my nvme0n1p2, is a bad typo sorry.

This allow me to boot and progress. I change the grub option to change UUID to /dev/nvmeXXX in the boot command line, and it's working

This is my new kernel config who is hopefuuly better :

Now, how can i get rid of the error with amdgpufb and the framebuffer to have a moduleless kernel ?

If i understand correctly having a custom initrd (who doesn't impact framebuffer, correct ?) is not gone change anything ?

I still have my artix and i have this difference which, i think could be interesting :

I stumbled into a similar situation today.

According to AMDGPU Wiki you have to put the firmware blobs into the kernel or into the initrd in case you built amdgpu fix into the kernel and not as a module.

In my case (7900xtx):

@ musv i have done that if you look my kernel config post 4 or 11. My firmware "family" is dimgrey fish but they are there with the amd microcode.

i didn't expect one video card in particular, my uefi allow me two choice in this matter : hybrid or dedicated gpu.

i though, wrongfully it appears, that in hybrid mode the chipset graphic who would be chosen. so i clearly need to add the sardine firmware in my kernel (with the ethernet fix) am i correct ?

EDIT : i forget to say that even with my current situation i am able to boot and load an destop environment with some fallback driver probably

lessblonux1,

I have not seen a dual AMD hybrid arrangement before.

Hybrid usually means that the low power GPU, here Cezanne, is always active and the dedicated GPU helps out with the rendering.
To use both GPUs like that, you need to provide all the firmware.

The console will only use the low power GPU.

If you choose "Dedicated" in the firmware, it may just work as you have the firmware for the Navi 23 installed.
Then you use only that GPU.

Like I say, this is new ground for me.
Intel/nVidia goes back a long way. Intel/AMD is around too. AMD/AMD like this is new.
