Actualmente estoy configurando gentoo en una máquina nueva usando un SSD NVME de 500 Gb.
Reinicio mi computadora, selecciono el disco desde el que quiero arrancar, grub2 se inicializa,y luego, el error que me sale es el siguiente:
!!Block device UUID="9a89bdb4-8f36-4aa6-a4c7-831943b0985c" is not a valid root device...
!!Could not find the root block device in UUID="9a89bdb4-8f36-4aa6-a4c7-831943b0985c"

Finalmente, aquí está el contenido de mi etc/fstab:
# /etc/fstab: static file system information.
#
# noatime turns off atimes for increased performance (atimes normally aren't
# needed); notail increases performance of ReiserFS (at the expense of storage
# efficiency). It's safe to drop the noatime options if you want and to
# switch between notail / tail freely.
#
# The root filesystem should have a pass number of either 0 or 1.
# All other filesystems should have a pass number of 0 or greater than 1.
#
# See the manpage fstab(5) for more information.
#
# <fs> <mountpoint> <type> <opts> <dump/pass>
# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
#
# NOTE: Even though we list ext4 as the type here, it will work with ext2/ext3
# filesystems. This just tells the kernel to use the ext4 driver.
#
# NOTE: You can use full paths to devices like /dev/sda3, but it is often
# more reliable to use filesystem labels or UUIDs. See your filesystem
# documentation for details on setting a label. To obtain the UUID, use
# the blkid(8) command.

También hice lo siguiente para solucionar problemas:
- habilitar el soporte nvme en el kernel
- habilitar el soporte del sistema de archivos xfs en el kernel
- cargar grub sin rootfstype=xfs
- sustituir el UUID

Este problemano se aplica porque fue un problema del controlador USB. YÉsteTampoco fue de ninguna ayuda.

Eso no parece un mensaje producido por GRUB.
¿Quizás su GRUB realmente funciona bien, pero a su initramfs le falta algo esencial, como un controlador NVMe o un módulo de soporte de tipo de partición GPT (a menos que los haya integrado todos como fijos en su kernel, por supuesto)? Entonces, ¿tal vez sea el initramfs de Gentoo el que está fallando en algún tipo de modo de solución de problemas?
Parece que Gentoo tiene varias formas de crear un archivo initramfs: genkernelpuedes hacerlo o puedes usar dracut. Cual estas usando?
Es posible que desee escribir shellese mensaje y ver si los /dev/nvme*nodos del dispositivo están presentes o no, qué módulos del kernel están cargados, etc. Si su utilidad initramfs Creator aún no tiene soporte específico para los discos del sistema NVMe integrados, podría ser tan simple como simplemente decirle a la utilidad "el initramfs debe cargar los módulos nvme-core.koy nvme.koantes de intentar buscar el sistema de archivos raíz"; es posible que no pueda resolverlo automáticamente.
