Problem on booting LFS LiveCD

satimis · 10-28-2005, 06:04 AM

Hi folks,

Following;
http://www.linuxfromscratch.org/hint...-udev-nptl.txt

I finished building BLFS LiveCD and burned it on CD-RW, all files not being compressed except /usr which was compressed with squashfs; (ISO image size about 430MB)

compressed /usr as usr.sqfs
removed /usr
mkdir /usr
mount usr.sqfs /usr/
all went through without complaint

Now the adventure started. On booting it popup

Verify DM1 Pool Data
Boot from CD
ISOLINUX 3.11 2005-09-02-Copyright(0)
1994-2005 H.Peter Anviin
Missing parameter in Config file
Could not find kernel image : lfskernel
Boot:

It hung here.

Which Config file was referred? If .config of /usr/src/linux-2.6.11/ the directory has been removed including .config. If it needs the .config file where I shall I put it? (I have it saved on another partition)

Which kernel image it referred? At the end of recompiling kernel, I ran;
# cp arch/i386/boot/bzImage /boot/lfscdkernel && cp System.map /boot/

# cat /mnt/livecd/boot/grub/menu.lst

Code:

default 0
timeout 30
color green/black light-green/black

title LFS LiveCD
# root (hd0,5)
root
kernel /boot/lfscdkernel root=/ vga=795
title Windows
# rootnoverify (hd0,0)
chainloader +1

Remark: also tried "kernel /boot/lfskernel root=/ vga=795"

# cat /mnt/livecd/etc/fstab

Code:

# file system  mount-point    type    options                              dump  fsck
       		                                                             order

/dev/fd0       /mnt/floppy    auto    noauto,owner,kudzu                      0  0
usbfs          /proc/bus/usb  usbfs   devgid=14,devmode=0660                  0  0

Please shed me some advise where shall I check. TIA

Hi folks,

Further to my previous posting. After making following changes

1)
on /isolinux/
renamed "lfscdkernel" to "lfskernel"

2)
/isolinux/isolinux.cfg
adding "vga=795 desktop=twm" after "kernel lfskernel"

Re-burned CD-RW

Now this time PC started to boot but the warning "Missing parameter in config file" still there.

The PC continued to boot until after following lines;
VFS : Mounted root (ext2 filesystem readonly)
Freeing unused kernel memory : 216K freed
Warning unable to open an initial console
Kernel panic - not syncing : No init found
Trying passing init = option to kernel

Then it hung here. Please advise where shall I check. TIA

1st try to check if you have /dev/console and /dev/null, if not create it by entering
cd /dev
mknod -m 660 console c 5 1
mknod -m 660 null c 1 3

If that doesn't work it could be that the cd-rw is bad, try to burn it on a cd-r

Hi mr_demilord,

Tks for your advice.

Quote:

1st try to check if you have /dev/console and /dev/null, if not create it by entering

# ls -l /mnt/livecd/dev/

Code:

total 8
crw-------  1 root root 5, 1 Oct 26 21:30 console
lrwxrwxrwx  1 root root   11 Oct 26 21:38 core -> /proc/kcore

lrwxrwxrwx  1 root root   15 Oct 26 21:38 stdout -> /proc/self/fd/1

It is there.

I also checked follows;

# ls -l /mnt/livecd/sbin/ | grep init

Code:

-rwxr-xr-x  1 root root  31240 Aug  5 18:57 init
lrwxrwxrwx  1 root root      4 Oct 26 21:19 telinit -> init

About the configure file;
The original ".config" and the kernel source tree have been already deleted. However there is a "Config-2.6.11.12" on /isolinux. Its version number is the same but inside all items previously compiled changed.

# cat /mnt/livecd/isolinux/config-2.6.11.12 | grep BLK_DEV_LOOP
# CONFIG_BLK_DEV_LOOP is not set
# cat /mnt/livecd/isolinux/config-2.6.11.12 | grep SND_PCM
CONFIG_SND_PCM=y
CONFIG_SND_PCM_OSS=y

I copied its orginal ".config" overwriting it and burned another CD. Problem remained the same with the same warnings popup.

# ldd /mnt/livecd/bin/bash

Code:

        linux-gate.so.1 =>  (0x00fbb000)
        libreadline.so.5.0 => not found
        libhistory.so.5.0 => not found
        libncurses.so.5 => /usr/lib/libncurses.so.5 (0x06018000)
        libdl.so.2 => /lib/libdl.so.2 (0x009d3000)
        libc.so.6 => /lib/tls/libc.so.6 (0x00882000)
        /lib/ld-linux.so.2 (0x00868000)

# ls /mnt/livecd/lib | grep linux-gate.so.1
(No printout)
# ls /mnt/livecd/lib | grep libreadline.so.5.0
libreadline.so.5.0
# ls /mnt/livecd/lib | grep libhistory.so.5.0

# ls /mnt/livecd/lib | grep libncurses.so.5

# ls /mnt/livecd/lib | grep libc.so.6

I'm worring burning dozen of cd-r. So I use cd-rw first. If it works then I'll burn cd-r.

Hi mr_demilord,

Further to my previous posting, I made further test by mounting the BLFS LiveCD

# ls -l /mnt/cdrom/boot/

Code:

total 13792
-r--r--r--  1 root root    2048 Oct 29 17:11 boot.cat
-rw-r--r--  1 root root 1960044 Sep 28 15:21 bzImage-2.6.11.12-sound
-rw-r--r--  1 root root 2115610 Aug 28 22:33 bzImage-2.6.11.12-try2

-rw-r--r--  1 root root 2090310 Aug  5 20:24 lfskernel-2.6.11.12
-rw-r--r--  1 root root  948040 Oct 26 23:36 System.map
-rw-r--r--  1 root root 1009134 Aug  5 20:25 System.map-2.6.11.12
-rw-r--r--  1 root root  944178 Sep 28 15:22 System.map-2.6.11.12-sound
-rw-r--r--  1 root root 1015507 Aug 28 22:34 System.map-2.6.11.12-try2

I suppose "isolinux.cfg" is the config file at booting

# cat /mnt/cdrom/boot/isolinux.cfg

Code:

default livecd

label livecd
  kernel lfskernel vga=795 desktop=twm
  append initrd=initrd.gz root=/dev/ram0 init=/linuxrc
ramdisk_size=16384

EOF

Remark: "vga=795 desktop=twm" were added later

Please advise whether its content is correct? TIA
