Lenovo ThinkPad L14 Gen 5 - kernel panic

jflash

Hello!

I’m trying to boot a Lenovo ThinkPad L14 Gen 5 using the 2025-01-08 kernel. The only thing that somewhat works is bzImage, but loading it ends with the message:

“Kernel panic - not syncing: VFS: unable to mount root fs on unknown-block”

Where to start?

@jflash Can you make sure that you are using the Linux kernel version 6.6.69 and Initrd 2024.02.9 for FOG.
If you are using those versions and it still kernel panics, please boot into a linux live image, then in the terminal enter lspci and post that output on here.

@jflash We just released a new experimental kernel/init. Can you update both the kernel and initrd, they are versions 6.12.25 & 2025.02.0. Try those and let me know if it still kernel panics.

jflash

@rodluz Hello! Same problem:

Just in case, I’m providing some additional information:
I’m using FOG version 1.5.9. TFTP Server settings:

I downloaded this files and specified them in the settings, but I renamed them with the suffix 20252:
bzImage - bzImage20252
bzImage32 - bzImage3220252
init.xz - init20252.xz
init_32.xz - init_3220252.xz

And just in case, here are also the MikroTik settings that redirect to the FOG server:

Tom Elliott

@jflash Bootfilename should be snp.efi, or snponly.efi (if using UEFI booting) or one of the other ipxe files.

Having the bootfile be your kernel is likely the reason you’re seeing this issue.

jflash

@Tom-Elliott
Do I need to change this in MikroTik? I tried it in MikroTik, and the results were such that with snp.efi, snponly.efi, and ipxe.efi, the loading stops at the text: ‘iPXE initializing devices.’ Or do I also need to change something in the FOG settings?

Tom Elliott

@jflash so you changed it in mikrotek which is correct. however I believe your machines are also runnign with secure boot enabled, which often is what we see or somethign more along the lines of straight error loading, though freezing is more often what i recall from Lenovo, at least long ago when I first started seeing them.

jflash

@Tom-Elliott
Hello again! Since I need to clone 60 laptops, I really hope to get this thing working Secure Boot is disabled, but I made a short video of my laptop’s BIOS settings—maybe there’s a small detail there that I’m overlooking
BIOS settings video

rodluz

@jflash Thank you for the video. I don’t see anything that jumps out at me that is wrong.
I created another kernel on my repo to try. https://github.com/rluzuriaga/fos/releases/tag/EXP_20250430

If that doesn’t work, maybe you could try disabling Securlty -> Memory Protection -> Execution Prevention.

If the memory protection setting doesn’t fix it, could you post the output of lspci -nn by booting into a linux environment on that computer? (Sorry I forgot the flags last time I asked)

jflash

@rodluz Still no luck New output:

Can you try with the realtek.efi file?

@Tom-Elliott Here is output:

@jflash I was just rereading through the full post and noticed a couple things.

I’m using FOG version 1.5.9. TFTP Server settings:

This is a really old version of FOG. I would recommend upgrading to the latest stable release.

From the last picture, your iPXE version should be updated too. @Tom-Elliott Can correct me if I’m wrong, but the iPXE version will update when you update FOG.
