 Posted: Mon Feb 24, 2025 6:19 pm Post subject: [Boot] I can't boot gentoo in new computer with Nvme (Open) |
 |
|
Hello.
Recently I bought a new laptop and I wanted to install gentoo linux inside. This laptop use NVMe for hard disk. I have follow the handbook like other times before. The unique point that i did difererent is with the kernel.I wanted configure the kernel like other times, emerging gentoo-sources and configuring by hand. I don't know if this is possible today or if I have to change the way I install/configure the kernel.
This to autodetect modules that was using for livecd environment:
| Code: |
# make localmodconfig
|
and select other devices with
select, save, whith:
| Code: |
# make && make modules_install && make install
|
The problem is after install grub2 and configure him. The computer is not possible to boot, this message error is:
| Code: |
md: Waiting for all devices to be availbe before autodetect
md: If you don't use raid, use raid=noautodetect
md: Autodetecting RAID arrays

My .config kernel file:
| Code: |
https://pastebin.com/fht3FfAB
|
Why with this grub configuration appear initrd image option??? In my previous gentoo installation, 4 or 5 years ago, never I have used initrd option to load kernel image in grub configuration...
Can someone help me?
Thanks.

If you insist on not having an initramfs make sure that ext4 and nvme module is in-built in the kernel.
| Code: |
CONFIG_EXT4_FS=y
CONFIG_BLK_DEV_NVME=y
|
The output you are getting refers to the amd firmware initramfs, NOT your actual initramfs.
| Code: |
initrd /boot/amd-uc.img
|
If i were you i would strongly use an initramfs.Pick up dracut.Its fabulous.

Hello.
Thanks alamhant for your help.
I have checked this, and is correct
| Code: |
livecd /usr/src/linux # cat .config | grep CONFIG_EXT4_FS
CONFIG_EXT4_FS=y
|
| Code: |
livecd /usr/src/linux # cat .config | grep CONFIG_BLK_DEV_NVME
CONFIG_BLK_DEV_NVME=y
|
I don't understand exactly what initrd is for and I've never needed it to run my various Gentoo machines. Maybe now I do? What exactly does it do?

| Try adding rootwait=5 to the command-line options (near root= or ro) as NVMe devices are added asynchronously and a panic may occur if the kernel is looking for root while it is still being populated. |

This is done by make localmodconfig, that's it purpose.

/boot/kernel-6.6.74 seems odd, what "instalkernel" set-up are you using? When you use | Code: | | USE="-*" emerge sys-kernel/installkernel |
make install does more* than just copy the bzimage file.
Once you get it booting you are better off losing the ucode images from /boot/ and just including "amd-ucode/microcode_amd_fam17h.bin" in CONFIG_EXTRA_FIRMWARE (the 17h is the hex value of "cpu family" from /proc/cpuinfo, I think you are 17h, well 23). You'll want the amdgpu/<firmware files> in there too, so (assuming I got the right cpu/gpu combo) | Code: | | CONFIG_EXTRA_FIRMWARE="amd-ucode/microcode_amd_fam17h.bin amdgpu/green_sardine_asd.bin amdgpu/green_sardine_ce.bin amdgpu/green_sardine_dmcub.bin amdgpu/green_sardine_me.bin amdgpu/green_sardine_mec2.bin amdgpu/green_sardine_mec.bin amdgpu/green_sardine_pfp.bin amdgpu/green_sardine_rlc.bin amdgpu/green_sardine_sdma.bin amdgpu/green_sardine_ta.bin amdgpu/green_sardine_vcn.bin" |
TBH, CONFIG_EXTRA_FIRMWARE is such a chore to alter in menuconfig it's the main one I do by hand in an editor.
| ZaPa wrote: | | What exactly does it do? |
It's basically to load modules that you need to boot, and do "other things" that the kernel can't w/o access to things it can't access at that stage in the boot process. As someone who doesn't even have loadable module support in most of my kernels, the only legitimate use case I'd have would be an encrypted root partition.
*Installkernel can try to re-create /boot/{intel,amd}-uc.img every time you run make install, the easiest way I've found to stop this is to just mute the the scripts if it does | Code: | echo '#!/bin/bash
exit' |tee /etc/kernel/preinst.d/35-intel-microcode.install > /etc/kernel/preinst.d/35-amd-microcode.install |
I don't know what causes this, mine doesn't do it, I've just been running triage on a bunch of machines I didn't install is all. |

Hello, thanks for your messages.
As I said before, I didn't use installkernel.
I just did emerge gentoo-sources and configured the kernel by hand and then make && make modules_install && make install to copy the kernel image to /boot. (I have follow this way always with all my gentoo installation)
About the name of image of kernel, I changed it myself, since if I left the default name generated by make install 'vmlinuz' when doing a grub-mkconfig it simply didn't detect the image.
Through this link: https://forums.gentoo.org/viewtopic-p-8765343.html?sid=20a0503872cf5d61732216ef3e8575b5 I found that changing the name and putting kernel-x-x grub detected the image. And so it did.
@grknight I have tried adding rootwait=5 in the grub config file and it didn't work.

Is nvme turned on in the kernel config and is it built in?

With another installations of gentoo (some years ago), my partitiion schema was different. /boot was in a partition and other partition for operative system..
In this schema, /boot/ y / are in the same partition.... ¿could be here the problem?

I wouldn't think you need more selected than the few that I have.
I would turn off the AUTH, and TARGET* stuff to start with, you should not need them.
