Rebuilding the kernel is a quite simple operation.
First, prepare the build directory:
cd /usr/src
tar -xjf /mnt/cdrom/usr/src/kernel/linux-2.6.18.tar.bz2
ln -sf linux-2.6.18 linux
cd linux
zcat /mnt/cdrom/usr/src/kernel/linux-2.6.18-*.diff.gz | patch -p1
zcat /proc/config.gz > .config
Now configure and build the kernel:
make menuconfig
make
Then install it:
cp arch/****/boot/bzImage /boot/linux-2.6.18-test
The "****" stands for your architecture name.
Configure bootloader (I did it once and always have "stable" and
"experimental" kernels):
image=/boot/linux-2.6.18
label=good
root=/dev/sda1
read-only
image=/boot/linux-2.6.18-test
label=test
root=/dev/sda1
read-only
append="panic=5"
Note the "append" parameter - if kernel will be unable to run init,
it will reboot in 5 seconds.
Reinstall the bootloader:
lilo
Ask the bootloader to load experimental kernel on next boot:
lilo -R test
Reboot with your new kernel:
reboot
