（Resolved） Manually compiled kernel cannot be started

[wlmosv]

Guys, after I manually configure the kernel. Can't boot I noticed it doesn't have an initramfs file but I'm not sure if that's the cause Now when I update the kernel I always have to use genkernel to update I don't like this

Code: Select all

wlmosv@localhost /boot $ ls
EFI                              initramfs-6.11.4-xanmod1-x64v2.img  kernel-6.11.4-xanmod1-x64v2  kernel-6.12.3-gentoo
System.map-6.12.0-gentoo-x86_64  initramfs-6.12.1-gentoo-x86_64.img  kernel-6.12.0-gentoo         vmlinuz-6.12.0-gentoo-x86_64
System.map-6.12.1-gentoo-x86_64  initramfs-6.12.1-gentoo.img         kernel-6.12.0-gentoo-x86_64  vmlinuz-6.12.1-gentoo-x86_64
grub                             initramfs-6.12.3-gentoo.img         kernel-6.12.1-gentoo-x86_64  vmlinuz-6.12.1-gentoo-x86_64.old
wlmosv@localhost /boot $ eselect kernel list 
Available kernel symlink targets:
  [1]   linux-6.6.62-gentoo-dist
  [2]   linux-6.11.4-xanmod1-x64v2
  [3]   linux-6.11.9-gentoo-dist
  [4]   linux-6.12.3-gentoo *
wlmosv@localhost /boot $ uname -r
6.12.1-gentoo-x86_64
wlmosv@localhost /boot $ 

You can see that my boot directory looks like this. I don’t know what caused this. Here is my kernel configuration file.
http://0x0.st/Xhiy.config

I want to install 6.12.3 now but can't. Can anyone help me find out what's going on?

Can't boot [...]
I want to install 6.12.3 now but can't.

And the new kernel fails how?

[...] I noticed it doesn't have an initramfs file [...]

There is a file named initramfs-6.12.3-gentoo.img in /boot, isn't that an initramfs for the 6.12.3 kernel?

You can see that my boot directory looks like this.

Code: Select all

wlmosv@localhost /boot $ ls
...
wlmosv@localhost /boot $ eselect kernel list
Available kernel symlink targets:

  [4]   linux-6.12.3-gentoo *

Many old kernels lying around. Also:

Code: Select all

wlmosv@localhost /boot $ uname -r
6.12.1-gentoo-x86_64

You have a file named kernel-6.12.1-gentoo-x86_64 and a file named vmlinuz-6.12.1-gentoo-x86_64 in /boot, is one of them a symbolic link?

wlmosv,

maybe I'm wrong, but it sounds to me like you used to create your kernels with “genkernel” and now you want to install a kernel completely manually (which I think is a good idea). In this case you only need an initramfs IF your root partition is encrypted. If it is not, you can easily configure, create (make) and install (depending on whether you have a bootloader/bootmanager or boot your kernel directly via UEFI) a kernel manually WITHOUT initramfs .

Thanks a lot. Now everything is working fine. Actually I don't have many ideas. I just don't like genkernel to prepare everything for me. Now everything is working fine. Thank you.
