LinuxQuestions.org - kernel panic on boot

- - kernel panic on boot (https://www.linuxquestions.org/questions/slackware-14/kernel-panic-on-boot-4175530682/)

Well, I see parts of both (Grub and LILO) bootloaders installed.
Do you remember, which one do you installed and configured during installation?
what does

Code:

ls -l /media/boot/grub

shows?

And what is the output of

Code:

cat /media/etc/lilo.conf

command?

Please, wrap the outputs into tags . It helps a lot to read your posts.

OK, now better ?

Thanks, see you.

mount /dev/sda1 and post what is on it.

What might be there? It's a swap. I doubt ls will show anything on swap partition:

Code:

Device Boot Start End Blocks Id System

/dev/sda1 2048 4196351 2097152 82 Linux swap

@xavi_slacky
Since you are using huge kernel it shouldn't be a kernel module issue (assuming you are using Live media with the same kernel).
And I see that you have both Grub and Lilo installed. It might cause a mess.
Your lilo.conf seems fine, and points to correct partition, so I'd suggest to chroot into your installation from live media and run "lilo" once more. Keep in mind, you have to run "lilo" command on every lilo.conf changes.
Exit chroot, shut down PC (do not forget to detach any usb sticks that attached, they might change drives enumeration order) and try to boot.

Added:
How to chroot:
Boot with your media, open terminal and run as root:

Code:

mount /dev/sda2 /mnt

mount -t proc none /mnt/proc

mount -o bind /dev /mnt/dev

mount -o bind /sys /mnt/sys

chroot /mnt /bin/bash

liloconfig

lilo

exit

When running liloconfig, at this stage:
http://i.imgur.com/paEx2nQ.jpg
select "Skip" option.
And at this stage:
http://i.imgur.com/Y6uB7fg.jpg
select "MBR".
When liloconfig exited (cursor at command line starts to blinking), continue with "lilo" and "exit"

Using this ISO I installed Slackware and booted.

Misread the partition table was looking for the efi patition and if there is an elilo configuration file and if so what was in it.

For me, /dev/sda1 is my Linux swap partition.

I try with /dev/sda2 which is my Linux root partition.

I don't get LILO ncurses menu.

I following yours step to step but I get same initial issue.

More ideas ?

Thanks, see you.

You could try running pkgtool from the chroot and try to reinstall lilo.

How new is your system? Do you know if it is UEFI or is it BIOS based? If it is UEFI, we'll work on ELILO, if it is BIOS based, we'll work on regular LILO. Knowing this should help us better help you.

Also, did you do a full install of Slackware?

I try running pkgtool from chroot but, I don't know install LILO from USB stick installation.
How can I install it from pkgtool on chroot ?

Thanks, see you.

I have UEFI BIOS boot option.

How can I install ELILO ?

Yes.

Thanks, see you.

In pkgtool go to "setup" then in the list find lilo (or elilo if you have an uefi mobo).

If you aren't forcing UEFI right now and are doing a BIOS emulation, it may be easier to just stick with BIOS and using LILO. If you decide to stick with this route, what happens if you do the following (after booting off the Slackware install disc)?

Code:

mount /dev/sda2 /mnt

mount -o bind /dev /mnt/dev

mount -o bind /proc /mnt/proc

mount -o bind /sys /mnt/sys

chroot /mnt

lilo -vt        #this just does a test run of everything to show you any warnings that may crop up post the output of this

[/code]

If the lilo test seems to run fine without any errors (there might be a warning about LBA32, which you can safely ignore), then you can go ahead and run lilo without any arguments. If you're not sure if the output is an error or not, feel free to paste it here and we can let you know.

If this doesn't work, you may already be running in UEFI mode, but if you didn't partition for /boot/efi, then you're going to run into problems. See the README_UEFI.TXT on using UEFI on Slackware.

http://slackbuilds.org/mirror/slackw...EADME_UEFI.TXT

Also, this may be considered nitpicking, but it is much easier to see what you're replying to if you encase it in quote tags (square brackets [word] around the word (replace word with quote) at the start and square brackets around the word with a fordward slash in front of it at the close [/word]). To me, it is a bit jarring to see the > greater than symbol on a forum (since I hardly even see it in email anymore thanks to gmail).

Quote:

liloconfig doesn't show ncurses menu? Did you really run it from chroot?

You can install Grub instead of LILO, I replaced LILO with Grub using the same Slint ISO. And I created here exactly the same partitions layout: sda1 is swap and sda2 is root (/).
Try this when booted into Slint live system:

Code:

mount /dev/sda2 /mnt

mount -t proc none /mnt/proc

mount -o bind /dev /mnt/dev

mount -o bind /sys /mnt/sys

chroot /mnt /bin/bash

grub-install /dev/sda

grub-mkconfig -o /boot/grub/grub.cfg

exit

Now I have Grub bootloader instead of LILO. Grub menu looks a bit different than LILO, but it doesn't matter.
If you can't install Grub, it might be due to inconsistent Slint ISO.
Anyway, try the code above.

Well xavi_slacky, as you used a Slint installer, I assume that I ought you some support or after sales service ;)

First, please confirm that :

you downloaded the 32-bit image
you checked the integrity of the ISO using the md5sum before writing it on a DVD or USB stick

Then please boot again the installer and once logged in provide the output of following command:

Code:

lsblk -o name,type,model,size,fstype,mountpoint,label,uuid

Then, please indicate how you intend to use each of the partitions listed. Hopefully this will help us to help you.

As others have pointed out, to make the text you copy here easier to read, please place the results of the command inside code tags. In the same vein, when you quote another post, please use the quote tags.
