LFS is not booting up

I finish LFS book and when I wan't boot to my LFS system show me rest_init+0x60/0x60 error

Attachment 16782

Maybe post your lfs fstab file and your grub.cfg file. What partition is lfs on

this is My fstab File

Code:

# Begin /etc/fstab

# file system  mount-point  type    options            dump  fsck

#                                                              order



/dev/sdb2      /            ext4    defaults            1    1

proc          /proc        proc    nosuid,noexec,nodev 0    0

sysfs          /sys        sysfs    nosuid,noexec,nodev 0    0

devpts        /dev/pts    devpts  gid=5,mode=620      0    0

tmpfs          /run        tmpfs    defaults            0    0

devtmpfs      /dev        devtmpfs mode=0755,nosuid    0    0



# End /etc/fstab

and grub.cfg

Code:

# Begin /boot/grub/grub.cfg

set default=0

set timeout=15



insmod linux

set root=(hd0,msdos2)



menuentry "GNU/Linux, Linux 3.17.1-lfs-SVN-20141026" {

        linux  /boot/vmlinuz-3.17.1-lfs-SVN-20141026 root=/dev/sda2 ro

}

Did you try

Code:

menuentry "GNU/Linux, Linux 3.17.1-lfs-SVN-20141026" {

        insmod ext2

        set root=(hd0,msdos2)

        linux  /boot/vmlinuz-3.17.1-lfs-SVN-20141026 root=/dev/sda2 ro

}

The fstab says root should be /dev/sdb2.
The grub.cfg says root should be /dev/sda2.

Where's your swap partition being mounted at in fstab?

I try it now. this is New output

Did you adjust your fstab as stoat pointed out
Presumming lfs is on sda2

how can I do that

So what partition did you put lfs on sda2 or sdb2/

sdb2..

So on a usb drive then your grub,cfg is wrong. Can you post grub.cfg again pls

This is my grub.cfg file

Code:

set default=0

set timeout=5



set root=(hd1,msdos2)

insmod linux



menuentry "PersianOS, Linux 3.17.1" {

        linux  /boot/vmlinuz root=/dev/sdb2 ro

}

Are you still getting the same error when trying to boot. You could try adding a root delay to grub.cfg

[code]set default=0
set timeout=5

menuentry "PersianOS, Linux 3.17.1" {
set root=(hd1,msdos2)
insmod ext2

linux /boot/vmlinuz-3.17.1-lfs-SVN-20141026 root=/dev/sdb2 root-delay=20 ro
}

When you added your partition type into the kernel, did you enable it as a module or built-in?

I enable it as module.

I don't have any initrd.img file and I think this is my problem. how can I fix it?

I dont see any entries in there for lfs?

How and where did you install grub. or are you using the host grub

In order for your system to boot, you would need to build the file system support as built-in. The reason for the kernel panic is because the kernel can't load the device driver for your file system to read the system drive.

You'll basically never modularize file system drivers.

I had a similar problem.. i think when you see (0,0) you're missing something for your hd into the kernel or, as suggested, you have to go with * instead M

I intall grub at /dev/sda and /dev/sdb

Hi did your change your ext4 fs in the kernel to built in?
as Reaper mentioned

No...

Can you grep the config file,

Code:

cat /boot/config-what-ever | grep CONFIG_EXT4

The red bit not sure what config you have "the book is showing 3.16.2"
Post the output

Post the output

Code:

CONFIG_EXT4_FS=y

CONFIG_EXT4_USE_FOR_EXT23=y

CONFIG_EXT4_FS_POSIX_ACL=y

CONFIG_EXT4_FS_SECURITY=y

# CONFIG_EXT4_DEBUG is not set

Thats correct for the file system, Are you using the grub.cfg thats in post #18

If so just try using this

Code:

set default=0

set timeout=5





menuentry "PersianOS, Linux 3.17.1" {

set root=(hd1,msdos2)

insmod ext2





linux /boot/vmlinuz-3.17.1-lfs-SVN-20141026 root=/dev/sdb2 root-delay=20 ro

}

can you post

Code:

ls /boot

Code:

System.map-3.17.1 config-3.17.1 grub vmlinuz-3.17.1-PersianOS-1.0

grub.cfg

Code:

set default=0

set timeout=5





menuentry "PersianOS, Linux 3.17.1" {

set root=(hd1,msdos2)

insmod ext2





linux /boot/vmlinuz-3.17.1-PersianOS-1.0 root=/dev/sdb2 root-delay=20 ro

}

try using this

I try it but My LFS system isn't boot

Hi

I take it you renamed the kernel to this "vmlinuz-3.17.1-PersianOS-1.0" from what was in the book? and that is the kernel for lfs?

I would check that the correct drivers are set in the "kernel" for your "usb" hubs etc, according to the output from

Code:

lspci

Hi I install linux kernel again and show me this Error

Code:

No Working init found. Try passing init= option to kernel.

what grub.cfg are you using?

Ok maybe install an initramfs from here
http://www.linuxfromscratch.org/blfs...initramfs.html

you,ll need to install cpio

from here
http://www.linuxfromscratch.org/blfs...eral/cpio.html

I have had to install it myself on a usb installed lfs.

Now I have root file system, does not exist error.But I use ext4 fs.

Did you add the initrd to the grub.cfg

Can you post ls from lfs/boot

Post your grub.cfg you are using is that on sda?

And with lfs partition mounted at /mnt/lfs
df -T from host

Code:

root:/# ls /boot/

I don't understand.

Begining to come to a loss what to do, there has to be something in the kernel config thats been missed

Make sure these are built into the kernel not modules

USB drivers for EHCI, OHCI, UHCI. Use only what your platform uses. (usb drivers section).
Include the USB mass storage driver in the kernel. (usb drivers section)
Make sure scsi disk block device driver is built in the kernel (scsi device drivers area.)
Make sure filesystem driver is in the kernel as well.

Why not grab the 'huge' kernel from slackware and try that at least it will narrow down the possible sources of error, because at the moment you can't tell if it's a kernel, grub or system problem, at least we all know the slackware 'huge' kernel includes everything including the kitchen sink, if your system boots with a known working kernel then you know that the problem is in your kernel config, if it doesn't then you can concentrate on grub and the rest of the system.
