Hello,
This is my first gentoo installation atempt.
I am trying to install gentoo on on my laptop wich has archlinux windows, ubuntu and sourcemage(not working) on it.
my grub bootloader is located in the /boot of my arch install.
I am triying to install install gentoo on a nvme ssd so i made sure i have all the nvme modules in my kernel.
When i try to boot i get this error message: block device /dev/nvme0n1p9 is not a valid root device
could not get the root block device in .

This is my "nano -w /etc/conf.d/modules"
Code:
  GNU nano 2.7.5                                  File: /etc/conf.d/modules                                           

# Linux users can define a list of modules for a specific kernel version,
# a released kernel version, a main kernel version or all kernel versions.
# The most specific versioned variable will take precedence.
# FreeBSD users can only use the modules="foo bar" setting.
#modules_2_6_23_gentoo_r5="ieee1394 ohci1394"
#modules_2_6_23="tun ieee1394"
#modules_2_6="tun"
#modules_2="ipv6"
#modules="ohci1394"

# Linux users can give modules a different name when they load - the new name
# will also be used to pick arguments below.
# This is not supported on FreeBSD.
#modules="dummy:dummy1"

# Linux users can give the modules some arguments if needed, per version
# if necessary.
# Again, the most specific versioned variable will take precedence.
# This is not supported on FreeBSD.
#module_ieee1394_args="debug"
#module_ieee1394_args_2_6_23_gentoo_r5="debug2"
#module_ieee1394_args_2_6_23="debug3"
#module_ieee1394_args_2_6="debug4"
#module_ieee1394_args_2="debug5"

# You should consult your kernel documentation and configuration
# for a list of modules and their options.
modules="nvme_core"
modules="nvme"
modules="nvmet"
modules="nvmet-rdma"
modules="nvmet-fc"
modules="nvme-loop"
modules="nvme"
modules="nvme-rdma"




this is my fstab:
Code:


# <fs>                  <mountpoint>    <type>          <opts>          <dump/pass>

I used "genkernel all --menuconfig" to compile my kernel and i made sure ext4 support was compiled in instead of module.
I also turned off all the amd settings in the kernel since i use intel and i added asus laptop extra other than that i changed nothing in the kernel.
Before that i tried the standard genkernel all and i got the same error and i also tried it with ext4 as a module.
I installed it from the ubutu environment because chrooting in arch does not work properly on other distros and installation media is really unconformable because this is the only computer i have at my disposal but i dont think this is an isssue.

Someone in the irc told me that my modules where wrong so i edited my /etc/conf.d/modules:
Code:
  GNU nano 2.7.5                                                                                              File: /etc/conf.d/modules                                                                                                       

# Linux users can define a list of modules for a specific kernel version,
# a released kernel version, a main kernel version or all kernel versions.
# The most specific versioned variable will take precedence.
# FreeBSD users can only use the modules="foo bar" setting.
#modules_2_6_23_gentoo_r5="ieee1394 ohci1394"
#modules_2_6_23="tun ieee1394"
#modules_2_6="tun"
#modules_2="ipv6"
#modules="ohci1394"

# Linux users can give modules a different name when they load - the new name
# will also be used to pick arguments below.
# This is not supported on FreeBSD.
#modules="dummy:dummy1"

# Linux users can give the modules some arguments if needed, per version
# if necessary.
# Again, the most specific versioned variable will take precedence.
# This is not supported on FreeBSD.

Any kernel driver you need for booting should be built into <*> the kernel (not as a module <m>).

does your initramfs include the nvme driver?
If not, charles17 is correct for your case.

philipW,

Code:
block device /dev/nvme0n1p9 is not a valid root device
could not get the root block device in .

This is very telling, for what it does not say.
Between the 'in' and the full stop, your kernel listed all the block devices it can see. In this case, none at all.

Your bootloader has
Code:
    linux /boot/vmlinuz-4.10.0-35-generic.efi.signed root=UUID=683d13a8-80f0-44c7-b809-105210ffb34f ro quiet splash $vt_handoff
   initrd /boot/initrd.img-4.10.0-35-generic

and
Code:
      linux /boot/kernel-genkernel-x86_64-4.12.12-gentoo root=/dev/nvme0n1p9
      initrd /boot/initramfs-genkernel-x86_64-4.12.12-gentoo


Thats two different kernels and initrd.

It looks like the SCSI stack is missing from your kernel as it does not list any /dev/sr* devices.
That would be correct if you don't have any optical drives.

If your kernel does not hove the nvme drivers set as <*>, the initrd must load them. The modules file cannot be read until root is mounted, so its a kernel/initrd issue.

Your genkernel initrd should give you a shell if it can't mount root, not panic.
Look for your nvme device nodes in /dev from that shell.
If they are missing, I'll guess that genkernel does not build/load them.

philipW,

Missing

Code:
$ grep USB_PCI /usr/src/linux/.config
CONFIG_USB_PCI=y

Is needed for all USB on a PC

and or
Code:
$ grep XHCI /usr/src/linux/.config
CONFIG_USB_XHCI_HCD=y
CONFIG_USB_XHCI_PCI=y
and connecting to a USB 3 port are both popular.

philipW,

Modules work as long as you don't need to type the modprobe command. :)

Wait what my keyboard is not working.
Rebooted keyboard working again.
Booted into gentoo.
