kernel panic at start

f4rm0r · 2012-05-04 20:31:54

I have two big problems
1. I am trying to install a old kernel, because since the latest update it did not work, all I get is I am tossed to ramfs... (I am sure you have had LOTS of these posts, but please be patient)
as I am speaking I am chrooted from a live cd that is booted from RAM (and I did it using this guide
whenever I am trying to downgrade from this site: http://schlunix.org/archlinux/core/os/x86_64/
and downloading the kernel named: kernel26-lts-2.2.6.32.53-1-x86_64.pkg.tar.xz and then installing it using

 Pacman -U "way kernel"

whenever I do that, I get these errors:

==> Generating modules dependencies
install: cannot stat ´/lib/modules/2.5.32.53-1-lts/modules.builtin´ : No such file or directory
Warning: Could not open /tmp/mkinitcpio.2Quz6n/root/lib/modules/2.6.35.53-1-lts/modules.builtin: No such file or directory
==> Creating gzip initcpio image: /boot/kernel26-lts.img
bsdcpio: Failed to set default locale

and that can counclude all errors... since I am getting alot of output, but these are where the errors are.
2. I do not have internet on that computer since I cant use modprobe to load iwlagn? no errors while using modprobe straight from livecd, but whenever I am using iwlagn I am getting

 Error: Command not found

should I get this error even straight from livecd even though I had just used modprobe to load iwlagn?

PS: I am not a advanced user, so if you have any commands I need to write, that are not basic, please explain so I can learn what it does, and maybe I remember it next time this happens, thank you in advance

It seems a lot of posts lately are seeing downgrading as a good solution to problems. It is not. It can be suitable as a last resort, have you been working on what the problem was with the "latest update"? Was this latest update 3.3.4-1 or 3.3.4-2?

I belive it was in 3.3.4-1 because it was almost 2 months I had this computer on, but I thought that would give it a try now.
and I was using it as a last resort, since nothing I did, or read about when searching for problems on google

UPDATE:
when I start computer I get this output before bailing out to ramfs:

 :: Starting udevd...
/usr/lib/udev/udevd: line 2: syntax error: unexpected ";"
done.
: : Running Hook [udev]
: : Triggering uevents.../usr/bin/udevadm: line 13: syntax error: unexpected redirection

done.

ERROR: Unable to find root device '/dev/sda4'.
You are being dropped to a recovery shell
       Type 'exit' to try and continue booting
sh:   Can't access tty; job controll turned off
[rootfs /]#

this error I get when I am booting computer (obviously), even though I updated both udev and mkinitcpio to latest version without errors in chroot.
I can't update kernel to latest stable kernel from the official Arch site .
when I try to update kernel to latest kernel from arch site it says this:

 pacman -U "way to kernel"
loading packages...
resolving dependencies...
looking for inte-conflicts...
error: failed to prepare transaction (could not satisfy dependencies)
: : ndiswrapper: requires linu<3.3
: : virtualbox-archlinux-modules: requires<3.3
: : virtualbox-module: requires linux<3.3

do you have any idea of what it can be that causes this?

PS: for upgrading I use

 pacman -U "way to kernel"

since I cant modprobe for iwlagn on that computer (modprobe gives no errors, but when I try to use iwlagn it say command not found)

Apart from the kernel you will also need to download ndiswrapper, virtualbox-arxchlinux-modules and virtualbox-module , then issue a command like this :

pacman -U path/to/kernel path/to/ndiswrapper path/to/virtualbox-archlinux-modules path/to/virtualbox-module

I did what you said,and I got a couple of errors when I was installing, in a line to this:

 could not get file system information for /automount

and other several places, do you need these places too? this was the first place I got up
now I did

 mkinitcpio -p linux

hoping that it could work even though I got those errors; I got no errors from running this command ( I did not saw any errors, I think)
now when I am booting, kernel can't find udev

UPDATE:
I found a ethernet cable, so I ran dhcpcd and now I am connected to internet, so I am doing a full system update, though I am not updating pacman.
I am running pacman with:

 pacman -Syu --ignoregroup kde,xorg,gnome

I will post results when I am done

sorry that it took a hile for me to answer, school came in the way...

I updated my system to latest but it is still the same error, I did a full system update, but my computer still panic at computer start.
whenever i try to chroot from a live arch cd it says this:
(I write the whole chroot process I use, and the error message)

mkdir /mnt/arch
mount /dev/sda 4    (my root partition)
mount /dev/sda2     (my boot partition)
cd /mnt/arch
mount -t proc proc proc/
mount -sysfs sys sys/
mount -o bind /dev dev/
chroot /mnt/arch /bin/bash
/bin/bash: error while loading shared libraries: libcursesw.so.5 wrong ELF class: ELFCLASS32

and then nothing more happens, no more error messages or anything like that, if you want more like debug messages, please tell me how to give you that.

Check your mount commands, it should be like this :

mkdir /mnt/arch
mount /dev/sda4 /mnt/arch
cd /mnt/arch
mount /dev/sda2 boot/
mount -t proc proc proc/
mount -sysfs sys sys/
mount -o bind /dev dev/
chroot /mnt/arch /bin/bash

Also make sure the live arch CD uses the same architecture as your installation :
if you got 32-bit install, use a 32-bit live CD
for 64-bit install use a 64-bit live CD

and ofcourse I forget to write mount point
that was why it looked like I failed, but think about it, without mounting I would not have been able do cd into /mnt/arch

I re did it again, practically copy/pasting what you were writing, and no difference.
I have arch 64-bit installed, and my disc is for 64-bit
