Stuck at loading initramfs with the two good framebuffer

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

CONFIG_FB_VESA=y
CONFIG_FB_EFI=y

and there is no more CONFIG_FB_SIMPLE options

but even with the others removed specially

CONFIG_SYSFB_SIMPLEFB is not set
CONFIG_XEN_FBDEV_FRONTEND is not set

things doesn't. I also try to remove

CONFIG_SYSFB

but i can't

Symbol: SYSFB [=y] │
│ Type : bool │
│ Defined at drivers/firmware/Kconfig:229 │
│ Selects: BOOT_VESA_SUPPORT [=y] │
│ Selected by [y]: │
│ - FB_VESA [=y] && HAS_IOMEM [=y] && FB [=y]=y && X86 [=y] │
│ - FB_EFI [=y] && HAS_IOMEM [=y] && FB [=y]=y && !IA64 && EFI [=y] │
│ Selected by [n]: │
│ - SYSFB_SIMPLEFB [=n] && (X86 [=y] || EFI [=y])

I don't think it matters but i use musl, and i have a moduleless kernel.

Any help is appreciate.

lessblonux1,

Welcome to Gentoo Forums !

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

Code: Select all

Device Drivers --->
    Graphics support  --->
        Console display driver support  --->
            [*] Framebuffer Console support

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

Symbol: FRAMEBUFFER_CONSOLE [=y] │
│ Type : bool │
│ Defined at drivers/video/console/Kconfig:73 │
│ Prompt: Framebuffer Console support │
│ Depends on: VT [=y] && FB [=y] && !UML │
│ Location: │
│ -> Device Drivers │
│ -> Graphics support │
│ -> Console display driver support │
│ -> Framebuffer Console support (FRAMEBUFFER_CONSOLE [=y])

I have pasted in two parts my kernel config if someone can see what's wrong.

1) Haha ... YES ... look at (5)
2) From where you have copied this config ?
3) Good ... I recommend it also ... BUT it has some afteraffect you have to know ...
4) Is it an AMD NOTEBOOK ?!
5) You really should change this to the number of your LOGICAL CPU cores.
6) You dont need Intel stuff in an AMD machine
7) hmm ... ok ... no swap ...
8 ) hmm ... a monolithic kernel ... mine is also a monolithic one

9) Hopefully this is correct and nothing is missing.
10) ... REALLY ? ...
11) This does not work: From all 4 LSM which do MAC (selinux,apparmor,smack,tomoyo) you can use ONLY ONE: This one must be set as default. At the moment it is smack ... do you really use smack ? You can't because it is not in CONFIG_LSM
12) Good. You are using Gentoo hardened so I think you want security. Maybe you want read more in these two wiki articles:
https://wiki.gentoo.org/wiki/User:Pieti ... figuration
https://wiki.gentoo.org/wiki/User:Pieti ... _with_KSPP

I can say, it should not be a problem with framebuffer or console ... so ... maybe your kernel does panic and you dont see it. We had such a mystery problem also here: viewtopic-t-1161810-highlight-.html

To be honest ... I would throw away this config (there are many useless modules activated) and do a clean new one.

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.

It is a kernel command line paramter; with "nosmt" you can disable SMT/hyperthreading ->

All other LSM work together (yama,IMA,landlock,lockdown,loadpin,...) with ONE of the MAC LSM's. This is my line (I use apparmor and all these):

(landlock,lockdown,yama,integrity,apparmor,bpf)

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.

lessblonux1 · Post by **lessblonux1** » Thu Mar 23, 2023 5:03 pm

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.

dracut couldn't find the /dev/disk/UUID... this filesystem doesn't exist

I checked the uuid with blkid and it was the good in my fstab and in dracut so i am stuck again.

As i want to be sure my notebook is compatible with linux i have try succesfully to install Fedora and Artix with succes so i don't think there is a hardware problem

Post by **NeddySeagoon** » Thu Mar 23, 2023 5:14 pm

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

Code: Select all

root=/dev/nvme0p2

Now allow the system to boot. That's a one boot only change. The content of grub.cfg on disk is not changed.

DO you get a different error or does it boot now?

== edit ==

Code: Select all

root=/dev/nvme0p2

looks wrong. I have a /dev/nvme0n1p2
Are you missing a "n1" is your post?

lessblonux1 · Post by **lessblonux1** » Fri Mar 24, 2023 9:21 pm

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 :

https://dpaste.com/8DWQ2WW8B

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 ?

Post by **NeddySeagoon** » Fri Mar 24, 2023 9:54 pm

lessblonux1,

Your kernel has

Code: Select all

CONFIG_GENTOO_PRINT_FIRMWARE_INFO=y

What firmware gets loaded for amdgpu?
dmesg will tell.

Your kernel provides 12 amdgpu/dimgrey_cavefish_* which looks correct ... but is that what is actually being loaded?

Pastebin dmesg if you like. We all want to know the answer :)

-- edit --

The initrd won't change anything but is that something you need at all?
Perhaps that's a question for later.

here is my dmesg :

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):

Code: Select all

CONFIG_EXTRA_FIRMWARE="amd-ucode/microcode_amd_fam19h.bin amdgpu/psp_13_0_0_sos.bin amdgpu/psp_13_0_0_ta.bin amdgpu/smu_13_0_0.bin amdgpu/dcn_3_2_0_dmcub.bin amdgpu/gc_11_0_0_imu.bin amdgpu/gc_11_0_0_pfp.bin amdgpu/gc_11_0_0_me.bin amdgpu/gc_11_0_0_rlc.bin amdgpu/gc_11_0_0_mec.bin amdgpu/sdma_6_0_0.bin amdgpu/vcn_4_0_0.bin amdgpu/gc_11_0_0_mes.bin amdgpu/gc_11_0_0_mes1.bin"

No idea, if everything is needed. But at least it had been loaded by the initial genkernel.

@ NeddySeagoon :

i don't know if this is strange or not but my ethernet works well.
To be sure i am clear the dmesg i post come from my gentoo with amdgpu as module, if it wasn't i could be able to boot ^^.

Thanks again for the help as it seems a very complicated problem

lessblonux1,

Code: Select all

03:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Navi 23 [Radeon RX 6600/6600 XT/6600M] [1002:73ff] (rev c3) 
...
07:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Cezanne [Radeon Vega Series / Radeon Vega Mobile Series] [1002:1638] (rev c5)

You have two AMD video cards.
The Navi 23 card needs amdgpu/dimgrey_cavefish_* firmware, as you say.
The Cezanne card needs amdgpu/green_sardine_* firmware.

Which video card do you expect the console to appear on and why?

Do you want to use both cards later ?

The dmesg you posted shows no attempt to load the amdgpu driver at all.
Notice that dmesg does not show any driver in use for either card.

If you

Code: Select all

modprobe amdgpu

you may lose the console. Are you able to ssh into the system from another box so you can recover?
If not,

Code: Select all

shutdown -h now

not echoed to the screen, is the way out.

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.
