Estou tentando construir o kernel 4.13.2 para o void linux para obter os drivers Vega e não consigo inicializá-lo.
Processo de compilação:
cp /boot/config-4.12 .config
yes "" | make oldconfig
make nconfig
Changed processor type
Include ext4 by default
Made sure AMD drivers are included
make -j32 bzImage modules
make modules_install
System.map /boot/System.map-4.13.2
arch/x86/boot/bzImage /boot/vmlinuz-4.13.2
.config /boot/config-4.13.2
dracut -f /boot/initramfs-4.13.2.img 4.13.2
update-grub
Eu tentei basear a configuração a partir da existente, que inicializa bem.
Depois de um tempo, ele cai no shell de depuração dracut. O dmesg está cheio de "Verificando todos os dispositivos btrfs" até a mensagem "Não foi possível inicializar". Nem /dev/nvme* nem /dev/disk/by-uuid existe.
fstab:
/dev/nvme0n1p1 swap swap sw 0 0
/dev/nvme0n1p2 / ext4 defaults 0 1
/dev/nvme0n1p3 /home ext4 defaults 0 2
tmpfs /tmp tmpfs defaults,nosuid,nodev 0 0
Recebi alguns erros ao criar o initramfs, mas não vejo como eles estão relacionados:

Não sei quais são os próximos passos?
Eu consegui trabalhar pulando o initramfs e incluindo os módulos do kernel necessários no kernel.
Com lspci -kk | grep "Kernel modules" | sort | uniq eu poderia listar os módulos em uso atualmente e com eles em conjunto com a configuração padrão eu coloquei em funcionamento.
