Hi,
I am new to kernel compilation. I have never compiled a kernel before.
Today I said I must learn how to compile my kernel (who knows when I need it )

1) I downloaded the kernel from kernel.org (2.4.29)
2) a) make menuconfig
b) make dep
c) make bzImage
d)make modules
e) make modules_install
3) cp the new compiled kernel vmlinuz-2.4.29 in /boot
4) configure the boot manager (grub) to user the new compiled kernel.


I am using RedHat 9.
The problem is that when I boot with my new kernel I get the following error:

no socket drivers loaded
VFS: Cannot open root device "LABEL=/" or 00:00
Please append a correct "root=" boot option
kernel panic: VFS: Unable to mount root fs on 00:00


Does anyone know what I did wrong?
For my old kernel I also use initrd /boot/initrd-2.4.20-8.img

How I get a good initrd image for my new kernel? Where can I get it from? Do I need it? Can anyone explain me what is this initrd*.img

thanks

What about :
cp /usr/src/linux<version>/System.map /boot/System.map<version>
mkinitrd -o /boot/initrd-<version> /lib/modules/<version>
?

There is no initrd<version_of_my_new_compiled_kernel>.img in the boot directory. There is only an initrd_version_of_my_old_kernel.img.

Where can I get the initrd<version_of_my_new_compiled_kernel>.img?

tisam already told you. It's the 2 lines between "What about:" and "?".
And you shouldn't delete the old image nor its grub entry until you're not sure the new one is working as it should.

for solving the panic :unable to mount root fs, try to recompile the kernel 2.4.29
by including ""initalise from RAM"" in BLOCK DEVICES in the menu as a module.This might work.

plz reply to logtushar@rediffmail.com if this works.
