[ Kernel not booting up ]

[ashish raste]

Hi all,

Recently I compiled and tried installing kernel (2.6.39.3), which I
downloaded from kernel.org
All the activity that I did was to copy the .config file of my distro
(Ubuntu 10.10), then the following commands :

- make menuconfig ( I exited, keeping the default configuration )
- make modules
- make install_modules
- make install
- update grub

All of the above commands got executed without any errors, and the new
kernel version was also shown in the grub menu. But it showed some
errors and didn't login.

When I tried logging to my Ubuntu distro, a blue login box(which is
normally violet in color) appeared. After giving password, it came
back again to the same screen without going inside.

Only thing I was able to do was to dropping in root mode (from
Ubuntu's recovery mode u\in the grub menu) and looking at all of my
data through terminal without a GUI.

Can anyone tell how can I recover my compiled kernel and distro's kernel?

Thankyou.

hardly seems a kernel issue. its mostly an X related problem.
secondly, try to look into log messages e.g. dmesg and /var/log/message(not
sure about the location on ubuntu though)
thirdly, its possible that .config is incorrect.
with this info, one can hardly tell what is going on.

You can execute 'make localmodconfig' after this, to ensure that you have
all the necessary
components enabled in the .config file. It also strips off all the
unnecessary ones, which will speed up
your compilation.

Did you forget to run 'make' after this stage?

I run 'make modules_install' here...

If yes, you can try to boot your kernel by manually specifying the
path to your kernel image, initrd etc.
Eg:
grub> kernel /path/to/vmlinuz root=/dev/sda1
grub> root (hd0,0)
grub> initrd /path/to/initramfs_image
grub> boot

Note that you'll have to replace /dev/sda1 with path to your root partition.
And similarly
replace hd0,0 with the value appropriate in your computer's configuration.
[ hd0,0 refers to Hard-disk 0, partition 0, that is, the first partition on
your first hard disk. ]

Once you are able to boot into your OS fully, check your grub entries to see
if anything seems
to be wrong and fix them. The relevant file would be /boot/grub/menu.lst if
you are using the
old version of Grub (and not Grub2).

Can anyone tell how can I recover my compiled kernel and distro's kernel?

I didn't do a 'make localmodconfig' after this.

Yes, I ran make and make install_modules after this stage. Forgot
writing it in my previous mail.

I didn't see a prompt of grub> Instead the following errors were
listed on the black screen :

Hi Ashish,

 I am not sure if this will help but you can try burning a system rescue CD
and
using it to fix the issue. I believe you will be able to get back atleast
your original
Ubuntu with full GUI..

Hi Arshish!

Looks like you forgot to add support for your ATA/SATA controller.

I suppose you should boot up with any working kernel (maybe provided
with LiveCD) and use this config as starting point for your custom
building:

zcat /proc/config.gz > .config
make
and so on...

Any mistake in the configuration of your new kernel should not stop you from
booting from old kernel.
It seems from your mail that even your old kernel has stopped working !!! ..
If this is correct then this could be a problem of grub configuration.

I have tried rescuing, with sysrescue cd by burning it to a flash
drive and making it bootable.
But it showed at boot that "no kernel image found"
Anyways I have installed Ubuntu on the same partition and will try
compiling the kernel again!

Thankyou.
