 Posted: Sun Mar 31, 2024 10:23 am Post subject: Unable to make grub load a new kernel |
 |
|
I installed the new distribution kernel "linux-6.8.2-gentoo-dist" and was thinking that having "sys-kernel/installkernel" installed with grub USE flag should be enough to update grub and be done with it.
While the new configuration is generated in /boot, and the gubr.cfg looks updated, when rebooting the grub menu only gives the option of an old kernel: linux-6.5.5.
My /boot after installation of the new kernel can be seen here.
Thinking that the mess in the folder might be the issue, I cleaned it up to this, but the issue persisted (grub only showing 6.5.5).
The boot log from dmesg shows me "BOOT_IMAGE=/boot/vmlinuz-6.5.5-gentoo-x86_64" which doesn't exist anymore..
This makes me think that I'm actually looking at the wrong /boot but I don't see how that is possible.
My fstab should be fine and gives me the right partition:
| Quote: | /dev/nvme0n1p1 on /boot type vfat (rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mixed,errors=remount-ro)
|
The output of is: | Quote: | # efibootmgr

Does someone know what the issue could be?

I thought the grub config file is in /boot/grub/grub.cfg -- Are you checking the right location?
I also am not sure how you're installing grub, at least this is where I have my grub.cfg on my ESP which is mounted at /boot ...

I have =sys-boot/grub-2.12-r2 installed.
My grub config file is indeed in /boot/grub/grub.cfg, I was referring to the following files that are generated in /boot:
- config-6.8.2-gentoo-dist
- initramfs-6.8.2-gentoo-dist.img
- System.map-6.8.2-gentoo-dist
- vmlinuz-6.8.2-gentoo-dist |

It sounds like you may be installing the kernel and updating GRUB with the /boot partition not mounted. Use df to ensure the /boot partition is mounted and if not mount it and do it again.

so that should be fine |

When you run grub-mkconfig does it list your (old and) new kernels?

only the new ones:
| Code: | | grub-mkconfig -o /boot/grub/grub.cfg |
| Quote: | Generating grub configuration file ...
Found linux image: /boot/vmlinuz-6.8.2-gentoo-dist
Found initrd image: /boot/initramfs-6.8.2-gentoo-dist.img
Found linux image: /boot/vmlinuz-6.8.2-gentoo-dist.old
Found initrd image: /boot/initramfs-6.8.2-gentoo-dist.img.old
Warning: os-prober will not be executed to detect other bootable partitions.

Since apparently installing grub with the --removeable flag fixes some issue I tried to run:
| Code: | | grub-install --target=x86_64-efi --efi-directory=/boot/EFI --removable |
and then
| Code: | | grub-mkconfig -o /boot/grub/grub.cfg |
but that did no help either |

=sys-boot/grub-2.12-r2 seems to be quite some trouble. I do classic (non-UEFI-style) booting here and it locked me nearly out of the system (got weird errors at boot (kernel load) and things got stuck there) until I downgraded to 2.06-r9.
As of now (today?) there seems to be a Gentoo-patched revision 2.12-r3 to be in portage. Maybe this fixes something. But GRUB breakage is very nasty.

grub 2.12 seems to work fine for efi sorta though I ran into the setup problem. When I upgraded 2.06 to 2.12 I kept getting stuck in firmware setup. However after re-grub-install on my boot disk(s) everything went back to normal.
Seems the Gentoo devs are requesting a change to grub such that if you used the 2.12 grub-mkconfig for grub 2.06 EFI binary, it won't do this anymore... we'll see...
