Hello All,

Today I had an update where the kernel version was increased from 6.6.51 to 6.6.57. I am using the a distribution kernel.

I am using elilo and have updated by elilo configuration, to use the 6.6.57 version initramfs and vmlinuz files, but the kernel did not load. It froze at the first steps where it loads the vmlinuz and initramfs. It freezes after loading the intramfs file. The message "loading initramfs... done" is printed. But no scrolling kernel messages are displayed.

I reverted back to kernel 6.6.51 and writing this using that kernel.

eselect news list does not list any news relating to the current kernel version bump. There is a news item I have that dates back to 2024-08-09, and think this is not related to todays problem. Here is my eselect output

Code:

Please share the output of:

Code:
emerge --config gentoo-kernel


(or gentoo-kernel-bin if that is the one you are using)

Hmm ... I get: "The transfer you requested has been deleted." ... Maybe try another pastebin service.

Sorry for the inconvenience. I did not remember there was pastebin. Here is the link: https://pastebin.com/UWJS81E5

I don't see anything obviously wrong here. I suspect this is somehow an initramfs issue, have you tried re-generating the initramfs of the currently working kernel?

Did not try generating the initramfs (for 6.6.57).

I have configuration files in the /boot directory.

Code:
-rw-r--r--  1 root root   266812 Sep 23 05:58 config-6.6.51-gentoo-dist
-rw-r--r--  1 root root   267566 Oct 24 19:32 config-6.6.57-gentoo-dist


I think the difference in the kernels can be identified. Here is the difference between these two files.

Code:
diff config-6.6.51-gentoo-dist config-6.6.57-gentoo-dist

Do you see anything that might make the system hang after the initramfs is loaded (with a done message)? How much should I wait for the kernel to start?

I wonder if it's the same problem I had booting off an SSD with the kernel.org stable. That was 6.11.4, which corresponds to longterm 6.6.57.
If it is, the next update, 6.6.58, should cure it, as 6.11.5 cured it for me.

I have created a initramfs file using dracut for the 6.6.57 kernel using

Code:
dracut initramfs-6.6.57.1-gentoo-dist.img 6.6.57-gentoo-dist


The output of the command is as such:

Code:
dracut[I]: Executing: /usr/bin/dracut initramfs-6.6.57.1-gentoo-dist.img 6.6.57-gentoo-dist
dracut[I]: 90systemd-cryptsetup: Could not find any command of '/usr/lib/systemd/systemd-cryptsetup'!

dracut[I]: *** Creating initramfs image file '/boot/initramfs-6.6.57.1-gentoo-dist.img' done ***


The generated initramfs file size was different.

Code:
-rw-r--r--  1 root root 30861122 Oct 24 19:32 initramfs-6.6.57-gentoo-dist.img
-rw-------  1 root root 30860942 Oct 25 13:50 initramfs-6.6.57.1-gentoo-dist.img


But did not boot with that initramfs either.

Good to know. Thanks.

Can still use 6.6.51, and will stick with that then.

Hello Goverp.

I wanted to ask one more thing. I am going to install gentoo on a new x86-64 AMD device. Would the 6.6.57 kernel cause problems when installing? Not loading the kernel as it is the case with my old device.

Is dev-util/pahole installed? If not, then please try installing this package, and then re-installing gentoo-kernel-bin.
