'evening all, This morning I replaced the available kernels on this box. Previously I had 2.2.18pre21 from the original installation and 2.4.7-586 from installing kernel-image-2.4.7-586 (This is on a Debian Unstable system). I now have 2.2.19 and 2.4.10-586 from kernel-image-2.2.19 and kernel-image-2.4.10-586 respectively.
I edited /etc/lilo.conf by hand replacing references to 2.2.18pre21 and 2.4.7-586 with 2.2.19 and 2.4.10-586 respectively and ran lilo. The current version of /etc/lilo.conf is attached. I can boot using the 2.2 kernel OK but trying to boot using the 2.4 kernel fails wit a Kernel panic: modprobe: modprobe: Can't locate module net-pf-1 modprobe: modprobe: Can't locate module net-pf-1 modprobe: modprobe: Can't locate module net-pf-1 modprobe: modprobe: Can't locate module net-pf-1 modprobe: modprobe: Can't locate module net-pf-1 modprobe: modprobe: can't locate module block-major-3 VFS: Cannot open root device "304" or 03:04 Please append a correct "root=" boot option Kernel panic: VFS: Unable to mount root fs on 03:04 The net-pf-1 message is repeated so many times that all earlier messages have scrolled off the screen when the process halts. Typing linux-2.4 root=/dev/hda4 at the lilo prompt produces more or less the same result with an additional message about being unable to open hda4. /boot/vmlinuz-2.4.10-586 and /boot/initrd-2.4.10-586 exist as does /lib/modules/2.4.10-586/ Can someone point out what I have got wrong?

# /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 # 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/hda4 # 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 # install=/boot/boot.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. # # 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 prompt # single-key delay=100 timeout=100 # Specifies the VGA text mode at boot time. (normal, extended, ask, <mode>) # # vga=ask # vga=9 # vga=normal # Kernel command line options that apply to all installed images go # here.
