The efistub flag is not enabled, this is why it does not work.
This is an experimental feature, and the flag is stabled masked, to enable it you'd have to accept testing keywords for installkernel, uefi-mkconfig and dependencies. _________________ OS: Gentoo 6.10.12-gentoo-dist, ~amd64, 23.0/desktop/plasma/systemd

No, you use package.accept_keywords to accept testing keywords for installkernel and uefi-mkconfig, then enable the efistub flag, then re-install installkernel, then re-install the kernel. And then it *may* work, efistub booting is not guaranteed to work on every motherboard, many have quirks that make this impossible. There is no harm in trying though, this is all documented on the bootloader page of the handbook. _________________ OS: Gentoo 6.10.12-gentoo-dist, ~amd64, 23.0/desktop/plasma/systemd

you will need more for package.accept_keywords:

Here you will need another expert ... I never did the automatic way ... always the manual way ... because I want to know what's going on.
Your output from /boot is a little bit weird (please use code-tags for this) ... Do you have your ESP mounted to /efi OR to /boot/EFI ? Please show us a "ls -l" from your ESP (depending where it is).
Do you have the package "efibootmgr" ? If no, please emerge it, and then give us the output of:
You said you compile your kernel yourself: How made you the initramfs ? With dracut ?
I could take a look to your kernel .config if you want (please use wgetpaste for this). _________________ https://wiki.gentoo.org/wiki/User:Pietinger |

/etc/kernel/uefi-mkconfig
It should contain the kernel cmdline, it may be empty. _________________ OS: Gentoo 6.10.12-gentoo-dist, ~amd64, 23.0/desktop/plasma/systemd

IF ... if you have booted now WITHOUT grub ... THEN ... this is a good sign: UEFI has started your kernel.
Now we have to find out why you have a kernel panic. The most common reason is:
1. Kernel has not gotten the information where its root partition is ("root=..." as kernel command line parameter); please read: https://wiki.gentoo.org/wiki/User:Pietinger/Tutorials/Kernel_Commandline_Parameter
OR
2. Kernel cannot access root partition. This should not be possible when using an initramfs.
NOW: Boot with our GentooBootCD and chroot into your system and give us the output of "efibootmgr" and your kernel .config. _________________ https://wiki.gentoo.org/wiki/User:Pietinger |

Per Guidelines item #4, please give us output we can use. What is the output of blkid? Exactly how did you instruct the initramfs to mount root? |

pabloblo,
I have asked you to give me the output of “efibootmgr”. And I asked you if - and if so, how - you use an initramfs. You said you make your own kernel. But there are several ways to do this. We need the information what you have done ... and how.
The more precise your information about the situation is, the sooner and faster we can help you. An example:
The kernel panic "unable to mount root fs on unknown block" has usually some numbers in parentheses; e.g. (0,0) or (1,3) These numbers tell us something.
I have found the cause of every boot problem so far. If you want quick help, please just do now exactly what I ask for:
1. Boot into your system using grub
2. Give us all 3 files mentioned here:
https://wiki.gentoo.org/wiki/User:Pietinger/Overview_of_System_Information
(note the reference to wgetpaste for your "dmesg"-output)
3. Give us also your current kernel .config. If you have more then one used kernel, we need the kernel .config of the kernel you want to boot directly via UEFI (also with wgetpaste)
4. Do these queries (and paste it into your post):
- efibootmgr
- blkid
- lsblk
- fdisk -l
- cat /etc/fstab
- cat /boot/grub/grub.cfg (also with wgetpaste)
- ls -l /boot
- ls -l /boot/EFI -OR- ls -l /boot/efi -OR- ls -l /efi (depending where you mount your ESP)
5. Boot again into your kernel directly (via UEFI) and tell us the numbers you will see in the kernel panic message. _________________ https://wiki.gentoo.org/wiki/User:Pietinger |

If you dont know, then edit your 2nd (or 3rd) post of this thread and look at the beginning and the end of the code-section. It starts with [code] _________________ https://wiki.gentoo.org/wiki/User:Pietinger |
