Upgrade kernel 2.6.33 in ubuntu 9.10
1.Get the kernel source code of 2.6.33 from kernel.org.Patch the kernel if possible .
2.Extra the tar file,
$tar -xzvf linux-2.6.33.tar.gz
3.$cd linux-2.6.33
$sudo apt-get install ncurses //a text user interface library!
$make menuconfig
{
a good way for config the kernel !
it can easily get the hardware driver modules .
cp /boot/config-2.6.31-21-generic .config
$make old config
}
4.compile the kernel
$make bzImage
then
$make modules
then
$sudo make modules_install
it will copy the modules in /lib/modules/2.6.33 .
5.install the kernel
$sudo make install
it will run install.sh ,just copy three files into /boot directions
config-2.6.33
System.map-2.6.33
vmlinuz-2.6.33
6.create initrd image
$cd /boot
$sudo mkinitramfs -o initrd.img-2.6.33 2.6.33
or
$sudo update-initramfs -c -k 2.6.33
the 2.6.33 is the kernel release number ,just keep the same as vmlinuz-*,and /lib/modules/*
for it's a temporary file system ,so it contains some device drivers as the loadable modules ,
these modules must be copied by /lib/modules/2.6.33 directional .
7.configure the grub
alex@alex-laptop:/boot$ sudo update-grub2
