It look slike your kernel config is no good. Restore back to the 2.4 kernel, then try recompiling the 2.6. If you give some more detailed explenation of the "exact" error message you get, then maybe we could point out some things you need to look out for when compiling. From the basic info you gave however, it sounds like you compiled support for you root partition as modular ..which is a nono unless your are using an initrd.

hey guys
i found the problem with that kernel panic error message: i've installed my slackware on a logical partition. i've just deleted my windoze xpee cause it was on the primary partition and installed slackware on it. i have some more free time now so i will explain what happened now (not in a short posts as before).

i tried to compile my kernel again following the steps pointed in slackbook-2.0:
1. i've upgraded all the kernel packages and the alsa driver package.
2. and..

Code:

su
# cd /usr/src/linux
# make mrproper
# make menuconfig
blah blah
# make bzImage
# make modules
# mv /boot/vmlinuz /boot/vmlinuz.old
# cat arch/i386/boot/bzImage > /boot/vmlinuz
# mv /boot/System.map /boot/System.map.old
# make modules_install
# /sbin/lilo

everything went fine untill i ran /sbin/lilo. another error message was on my screen:

Quote:

Fatal: Can't find partition entry

i took a look at the man pages, but i found nothing. then i rebooted the system and again

Quote:

modprobe: Can't open dependencies file: /lib/modules/2.4.31/modules.dep ( No such file or directory )

in the changelog at slackwre mirror there was something about pointing the kernel version using depmod.
what else can i say.. Help please

Did you reboot after changing the partition table? If you did, what does your lilo.conf look like?

You need to either hardcode support oor your root partition into the kernel, or use an initrd to load up modular support for it.

i used fdisk to format my win partiotion and to create new linux one. i did this during the installation process when i booted my system from the slackware cd. after the installation was finished, i've rebooted.

and my lilo.conf:

Code:

# LILO configuration file
# generated by 'liloconfig'
#
# Start LILO global section
lba32 # Allow booting past 1024th cylinder with a recent BIOS
append=
boot = /dev/hda
message = /boot/boot_message.txt
prompt
timeout = 1200
change-rules
reset
# VESA framebuffer console @ 1024x768x64k
vga = 791
......
# End LILO global section
# Windows bootable partition config begins
other = /dev/hda5
label = Windows
table = /dev/hda
# Windows bootable partition config ends
# Linux bootable partition config begins
image = /boot/vmlinuz
root = /dev/hda1
label = Linux
read-only
# Linux bootable partition config ends

am i missing something

You have an entry for /dev/hda5 in /etc/lilo.conf -- do you actually have a bootable Windows partition there?

BTW, you really shouldn't run anything up to "make modules_install" as root. You also added extra steps that are really no longer necessary.

Try the following:

Code:

$ make menuconfig
$ make
$ su
# make modules_install
# cp arch/i386/boot/bzImage /boot/vmlinuz
# make install

Simple, easy, works (as long as lilo.conf is set properly)

That's not a bootable partition. i store my docs on it. should i remove it ?
thnx for the hint about that unnecessary stuff. i'll try that next time :P
