ubuntu boot problem after compiling new kernel

[Amirali Shambayati]

Hello all,
I compiled a new kernel according to
http://www.howtoforge.com/kernel_compilation_ubuntu instructions. The
kernel version is 2.6.18.1 and I did it in ubuntu 10.04 installed on
Virtualbox. But by choosing this kernel at grub, it gives this error:

libudev: udev_monitor_new_from_netlink: error getting socket: Invalid argument
Segmentation fault
Gave up waiting for root device. common problems:
-Boot args (cat /proc/cmdline)
-check rootdelay=(did the system wait long enough?)
-check root=(did the system wait for the right device?)
-Missing modules (cat /proc/modules: ls /dev)
ALERT! /dev/sda1 does not exist. Dropping to a shell!

I googled it and I looked for solution in many forums. I found some
solutions, but none of them worked for me :(
Such as checking if root device in grub is right for this kernel...
adding rootdelay=... to kernel line ... update-initramfs, adding
all_generic_ide to kernel line,...

My main kernel version is 2.6.32.21

Your help is appreciated. It's more than a week that I'm looking for a
solution. :-s

2.6.18.1 is more than 4 years old. Ubuntu 10.04 requires 2.6.32 or higher.
You need to use a newer kernel.

Use this tutorial: https://wiki.ubuntu.com/KernelTeam/GitKernelBuild

Thanks Chris and Anca,

I tried to compile latest kernel(2.6.37). but I receive an assembly
error: /include/trace/events/kmem.h:45: undefined reference to
'.L1747'. I didn't have any error at linux-2.6.18.1 compilation. I
read somewhere that kernel should be compiled by gcc-3.4 . Thus I
used gcc-3.4 to compile. Do you think it's a compiler issue? Should I
use another gcc version?
Sorry for asking stupid questions from you experts. I'm a newbie at
working with kernel.

Thanks in advance

Hi Amirali,

perhaps for 2.6.18* gcc-3.4* is used

but with 2.6.37 you could use the included gcc-4.4.3 (in Ubuntu 10.04)
and gcc-4.4.4
(according to http://distrowatch.com/table.php?distribution=ubuntu)

that worked fine for me in the past.

I don't know if you have full access to it but:

help.ubuntu.com - which is a sort of wiki for Ubuntu can be very
helpful in those things :)

https://help.ubuntu.com/community/Kernel/Compile

might help

If a pre-built vanilla-kernel is alright for you, you can also use the
ones provided by Ubuntu:

http://lwn.net/Articles/321473/
https://wiki.ubuntu.com/Kernel/MainlineBuilds?action=show&redirect=KernelMainlineBuilds

I hope that's what you're looking for

Regards

Matt
