If you can't boot with your kernel, you will need to adjust your settings, recompile the kernel, copy the new kernel to your boot partition and try again. Insert your install CD so you can boot to a working configuration. Once you reach a prompt, mount your partitions, devices and processes.
# mount /dev/sda3 /mnt/gentoo # mount /dev/sda1 /mnt/gentoo/boot # mount -t proc none /mnt/gentoo/proc # mount -o bind /dev /mnt/gentoo/dev
Chroot into the system environment.
# chroot /mnt/gentoo /bin/bash # env-update && source /etc/profile
Change your kernel settings.
# cd /usr/src/linux # make menuconfig
Compile your new kernel and copy the new image to your boot drive.
# make && make modules_install # cp arch/x86_64/boot/bzImage /boot/kernel
Umount your resources and reboot the system.
# umount /mnt/gentoo/boot /mnt/gentoo/dev /mnt/gentoo/proc /mnt/gentoo # reboot
