STUCK at first boot: LFS v9.0 First Boot Dell Inspiron 1545 Laptop

First time poster, first time builder! LQ.org has been a great help along way. I've put distros on my machines before, wanted to try to build from scratch on a spare machine I had laying around.

Specs on the machine:

Code:

Pentium T4400 @2.20Ghz 1067Ah "Penryn"

2 x 2G 800Mhz Dimms (4G DDR2 RAM)

82801M ICH9-M Southbridge Dell BIOS A13

GM45 Intel Integrated Video BIOS 1706, 32MB RAM

15.6" Display, 1366x768 Native display

IDT 92HD71 Audio

Broadcom BCM 4312 802.11b/g

500GB Disk, ICH9M E/M SATA AHCI controller

Alps Electric PS2 Mouse Glidepoint PNP0F13

Keyboard (Up Arrow and colon YUNO WORK?) [USB keyboard works fine]

ICH9 Family USB Controller



Target triplet: x86_64-pc-linux-gnu

Linker: lib64/ld-linux-x86-64.so.2

UEFI: No

I'm building LFS 9.0 for this machine, everything very basic, sticking with defaults where possible. I also went ahead and built the "useful" BLFS tools at the end of the book (like linx, openssh, wget, etc) and their dependencies, and recompiled the kernel with necessary support.

I installed grub to the MBR successfully, and when I rebooted the machine, I was greated with a grub menu, showing my LFS install on /dev/sda2/. Either highlighting it and pressing enter, or just waiting for the time out results in what appears to be the kernel loading. It goes by incredibly fast, I can't read any of it. Then the resolution changes to a larger one from whatever the boot default is. This is successful. No frequency out of range errors. It keeps on doing its thing for a couple more seconds then stops here (forgive any typos, I wrote this by hand, not sure how to get a log at this point):

The machine is not hung, just stopped with no interactive prompt. Pluging in USB devices results in messages printed to the console about the devices. Sticking a USB stick in with a live copy of mint, rebooting, and mounting my root partition, /dev/null exists and fstab shows /dev/sda2 mounted with "defaults" which should not contain "nodev"

I followed the steps really, really carefully.

Any ideas, or is it back around for another run?

EDIT: Here's a gem: https://www.thegeekstuff.com/2011/02/linux-boot-process

So, I shouldn't be googling "S45cleanfs permission denied" I should google, "init startup cleanfs permission denied". The game's afoot!

EDIT 2: Can I just put a chmod command on line 107 in the inittab file?

Looks like you haven;t done this bit:

Code:

mkdir -v {dev,proc,sys,run}

mknod -m 600 dev/console c 5 1

mknod -m 666 dev/null c 1 3

Here:
http://www.linuxfromscratch.org/lfs/...06/kernfs.html

Like the OP said, /dev/null node definitely exists. It also appears to have the correct permissions and is owned by root. All of the VFS directories exist. I really didn't skip that step, I promise.

U seem to have a lot /dev related failures maybe udev is broken?

If you look at the files that r causing the problem both errors come from redirecting to /dev/null it almost certainly isn't being created properly

A lot of udev failures? I only see one. How can I find out what's going on with /dev/null at boot? It looks fine from a rescue stick.

try booting to a different medium usb/cd etc check that delete every thing in dev and remake the null and console nodes, stat the nodes before and after and post them so WE know what their status is

Before replacing the nodes:

Code:

All looks fine the only thing I can think of is have you set these in your kernel config

Code:

CONFIG_UEVENT_HELPER=y

CONFIG_UEVENT_HELPER_PATH=""

CONFIG_DEVTMPFS=y

CONFIG_DEVTMPFS_MOUNT=y

And this in /etc/fstab

Code:

devtmpfs /dev devtmpfs mode=0755,nosuid 0 0

I used defconfig to start, then menuconfig for making changes while building the kernel. Where should I look for those options? Aaaaand, lemme go check on the that fstab line...

Try

Code:

gunzip < /proc/config.gz > /path/to/config

to get the configuration of the host machine, you should do this from the host you are building lfs on, you could also grab the slackware huge-config which covers just about everything, not at my machine now so can't help with where the config options are, you can of course edit the kernel config file with a text editor and then load it into the kernel menu config dialog.

AHA! devpts was mounted at /dev instead of /dev/pts
