Install Gentoo with systemd : kernel won't boot

[Adrien.D]

Hello,

I installed lots of Gentoo, but always with OpenRC, just 1 or 2 times with systemd.

Now we need to use "installkernel" tool to install kernel.

When i build my kernel, the system won't boot.
When i use the prebuilt kernel, the system boot.

I tried to use the config file of prebuilt kernel (i copied the config) and built with SAME config, the system won't boot.
I think the problem isn't the kernel, and not the configuration but other thing.

The system try to boot and blocked on "A start job is running for /dev/dis..db5550d452e46 (4min 20s / no limit)
After a long time, i enter to dracut shell.

I tried to use the "debian installkernel" ( https://wiki.gentoo.org/wiki/Installkernel#Debian.27s_installkernel so installkernel without systemd flag) but i can't have a system booted.

When i reboot on the prebuilt kernel, i don't have log on my root partition (to try to diagnose the issue)

The only thing i have to find the issue is this boot screen blocked to this state :

Can you help me ?

My config (which works on OpneRC) : https://pastebin.com/F7ZDxheP

Do you have lvm and/or luks in your setup ?
Dracut can't find your root device.
Do you use dracut to boot openrc gentoo ?
It seems to be dracut related ?
Some infos about the dracut config can be helpful.

Do you have lvm and/or luks in your setup ?
=> No, i usually use LVM, i tested in a VM with BIOS and only 1 / ext4 partition to exclude LVM issue

Dracut can't find your root device.
=> Looks like true. It's not a kernel panic, so i think the problem isn't the kernel, but i will try to search

Do you use dracut to boot openrc gentoo ?
=> Yes same installation : install kernel + grub (2) + dracut (generated by installkernel or manually)

It seems to be dracut related ?
=> Try to find

Some infos about the dracut config can be helpful.
=> No additionnal config for dracut, all set by default
