LILO and kernel panic


Previously, I was dual booting WinXP and SuSE 9.0 Pro, but recently, I've been trying out some othe Linux distributions in the place where Windows used to be. I just installed Slackware 10.1, and I'm having trouble booting to SuSE. I haven't touched the SuSE install, so it should (better) still be valid; in fact, a few days ago when Ubuntu was installed, GRUB would boot both Ubuntu and SuSE correctly.

Slackware installed LILO as the bootloader. LILO boots slackware fine, and will start booting SuSE, but part way through, I get an error along the lines of "Kernel Panic: No init mode found. Try passing "init=" to the kernel." Here's how my drives are set up:

hda1: / for Slackware 10.1. There are no other partitions on hda.
hdb1: /boot for SuSE 9.0 Pro
hdb2: NTFS partition with some documents from Windows on it
hdb3: swap (used by both Slackware and SuSE)
hdb4: / for SuSE

Here are the relevant sections menu.lst from a grub installation that worked (it correctly booted SuSE):
Code:
color white/blue black/light-gray
default 0
timeout 8
gfxmenu (hd1,0)/message

###Don't change this comment - YaST2 identifier: Original name: linux###
title Linux2.4.21
    kernel (hd1,0)/vmlinuz-2.4.21-286-default root=/dev/hdb4 vga=0x31a splash=si
lent desktop hdd=ide-scsi hddlun=0 showopts
    initrd (hd1,0)/initrd-2.4.21-286-default
And here is my current lilo.conf file (I've modified the SuSE section from how Slackware had set it up, in an attempt to fix the problem on my own, but I failed):

Code:
# Modified by YaST2. Last modification on Tue Mar 29 02:04:56 2005

  append="splash=silent desktop hdd=ide-scsi hddlun=0 showopts"
  label = SuSE
  read-only # Non-UMSDOS filesystems should be mounted read-only for checking
# Linux bootable partition config ends
I believe I've provided all of the relevant information, but if there's something I missed, let me know and I'll get you the output. Thank you.

Hello,
Shouldn't you have
root = /dev/hdb4
in lilo.conf instead of root = /dev/hdb1?

I just gave that a try, and no luck - I got the same errors as before. Also, when I run lilo as root with that lilo.conf, I get this as output:

Code:
root@matthew:~# lilo
Added Slackware *
Fatal: open /boot/vmlinuz-2.4.21-286-default: No such file or directory

I've tried several other things, and I'm still getting the same message. Any ideas?

it seems your slackware's /sbin/lilo just can't recognize your
SUSE's kernel image, you just mentioned /boot/blablabla
your system is rooting on your slackware root partition... that's the problem... it's checking on your slakcware /boot/ folder , not SUSE's

I've never tried this before, but try to copy your SUSE kernel image,+ meybe any other boot files needed, to your slackware /boot/ folder , and then run /sbin/lilo again.

hope it helps .. never used linux vs linux dual boot before...

try to remake the initrd file with the command mkinitrd. Rename the "/boot/initrd-2.4.21-286-default" to "/boot/initrd-2.4.21-286-defaultold" (backup). Get to a shell with /dev/hdb1 as root and type:

Code:
mkinitrd /boot/initrd-2.4.21-286-default kernelversion
You might neet to do:

Code:
lilo
in order to finish it off ( am not sure if this is requiered, it is probably not, but better safe than sorry)

that might help.

you might also want to try to use

Code:
lilo.conf
and try to install lilo again.
