Fui compilar o kernel em um ambiente limpo (so com o basicão do basicão), peguei as configs do /boot/config-version do debian e dei "make oldconfig" então retireis os:

CONFIG_MODULE_SIG, CONFIG_SYSTEM_TRUSTED_KEYS

para evitar do 'debian/certs/benh@debian.org.cert.pem' ser pedido durante a compilação, instalei os modulos, copiei o basico:

cp System.map /boot/System.map-version && cp .config /boot/config-ver && cp arch/x86_64/boot/bzImage /boot/vmlinuz-version

Instalei o grub e gerei seu arquivo de configuração:

grub-install /dev/sda && grub-mkconfig -o /boot/grub/grub.cfg

Considere o seguinte ao continuar lendo:
* Não estou usando debian, nem nenhuma distro que venha dele
* Não possuo Intramfs ou Initdr
* Esta compilação esta sendo feita por chroot
* O kernel panic possui um erro maior, entretanto acredito que o erro passado a seguir e o suficiente.

Ao bootar o hd que possui o sistema, levei um kernel panic:

not syncing vfs unable to mount root fs on unknown-block(0 0)

Desde ja, agradeço a quem puder ajudar.
