If your full message is:
kernel panic - not syncing: Attempted to kill inint !
PId: 1, comm: init not tainted 2.6.32.-279-5.2.e16.x86_64 #1
then you have to disabled selinux and after that, you have rebooted your system.
The easiest way is by using a live OS and re-enable it
vim /etc/selinux/config
...
SELINUX=enforcing
...
The 2nd choice is to disable the selinux in a kernel argument by adding selinux=0
vim /boot/grub/grub.conf
...
kernel /boot/vmlinuz-2.4.20-selinux-2003040709 ro root=/dev/hda1 nousb selinux=0
...
source kernel panic - not syncing: Attempted to kill inint !
