Alors ce que j'ai fait :

- ln -sfn linux-2.6.12.4 linux
- make mrproper
- cp config-2.6.12.4 .config ==> Je n'utilise pas mon config-<ancien_2.6> car plantage lors du make. Ce config-2.6.12.4 a été récupéré sur le site du tuto dont je me suis inspiré.
- make menuconfig ==> chargement du .config
- make
- cp arch/i386/boot/bzImage /boot/vmlinuz-2.6.12.4
- cp System.map /boot/System.map-2.6.12.4
- make modules_install
- mkinitrd -o /boot/initrd-2.6.12.4 2.6.12.4 ==> sous /lib/modules/2.6.12.4

boot=/dev/hda
root=/dev/hda1
map=/boot/map
prompt
timeout=15

default=Linux-2.6.12.4

# Noyau 2.6.12.4
image=/boot/vmlinuz-2.6.12.4
	label=Linux-2.6.12.4
	read-only
#	restricted
#	alias=1

	initrd=/boot/initrd.img-2.6.12.4

	read-only
	optional
#	restricted
#	alias=2

	initrd=/boot/initrd.img-2.6.8-2-386

- /sbin/lilo -v

Tout ca a l'aire correct, j'aurais remplace le "make" par:

make bzImage
make modules

cp autre_config .config
make

cp autre_config .config
make oldconfig
make

Version gcc-3.3.5

je fais tjs make mrproper et make menuconfig entre les recompile

Menu file systems

Tu as aussi:

Bonsoir

Moi aussi j'ai le même prob
J'était en 2.4.35 et j'ai recompilé les sources de 2.6.29 avec la config proposée dans les sources
La compilation s'est bien déroulée et j'ai fait les changements dans lilo pour pouvoir avoir le choix de démarrer en 2.4.35 ou en 2.6.29
Quand je démarre en 2.6.29 j'ai le probleme évoqué plus haut

Ma machine est équipée de disques IDE seulement et mon fstab est tout ce qu'il y a de plus simple

-----------------------
# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>

Voici mon lilo.conf

----------------
# /etc/lilo.conf - See: `lilo(8)' and `lilo.conf(5)',
# --------------- `install-mbr(8)', `/usr/share/doc/lilo/',
# and `/usr/share/doc/mbr/'.

# +---------------------------------------------------------------+
# | !! Reminder !! |
# | |
# | Don't forget to run `lilo' after you make changes to this |
# | conffile, `/boot/bootmess.txt', or install a new kernel. The |
# | computer will most likely fail to boot if a kernel-image |
# | post-install script or you don't remember to run `lilo'. |
# | |
# +---------------------------------------------------------------+

# Support LBA for large hard disks.
#
lba32

# Overrides the default mapping between harddisk names and the BIOS'
# harddisk order. Use with caution.
#disk=/dev/hde
# bios=0x81

#disk=/dev/sda
# bios=0x80

# Specifies the boot device. This is where Lilo installs its boot
# block. It can be either a partition, or the raw device, in which
# case it installs in the MBR, and will overwrite the current MBR.
#
boot=/dev/hda

# Specifies the device that should be mounted as root. (`/')
#
root=/dev/hda1

# Enable map compaction:
# Tries to merge read requests for adjacent sectors into a single
# read request. This drastically reduces load time and keeps the
# map smaller. Using `compact' is especially recommended when
# booting from a floppy disk. It is disabled here by default
# because it doesn't always work.
#
# compact

# Installs the specified file as the new boot sector
# You have the choice between: bmp, compat, menu and text
# Look in /boot/ and in lilo.conf(5) manpage for details
#
install=/boot/boot-menu.b

# Specifies the location of the map file
#
map=/boot/map

# You can set a password here, and uncomment the `restricted' lines
# in the image definitions below to make it so that a password must
# be typed to boot anything but a default configuration. If a
# command line is given, other than one specified by an `append'
# statement in `lilo.conf', the password will be required, but a
# standard default boot will not require one.
#
# This will, for instance, prevent anyone with access to the
# console from booting with something like `Linux init=/bin/sh',
# and thus becoming `root' without proper authorization.
#
# Note that if you really need this type of security, you will
# likely also want to use `install-mbr' to reconfigure the MBR
# program, as well as set up your BIOS to disallow booting from
# removable disk or CD-ROM, then put a password on getting into the
# BIOS configuration as well. Please RTFM `install-mbr(8)'.
#
# password=tatercounter2000

# Specifies the number of deciseconds (0.1 seconds) LILO should
# wait before booting the first image.
#
#delay=100

# You can put a customized boot message up if you like. If you use
# `prompt', and this computer may need to reboot unattended, you
# must specify a `timeout', or it will sit there forever waiting
# for a keypress. `single-key' goes with the `alias' lines in the
# `image' configurations below. eg: You can press `1' to boot
# `Linux', `2' to boot `LinuxOLD', if you uncomment the `alias'.
#
message=/boot/bootmess.txt

timeout=100

# vga=ask
# vga=9
#

# Kernel command line options that apply to all installed images go
# here. See: The `boot-prompt-HOWO' and `kernel-parameters.txt' in
# the Linux kernel `Documentation' directory.

Quelles modifications faut-il apporter pour corriger le problème

Thanks a lot
