I have been running fc2 server on my box. I tried upgrading to fc3, fc4, fc5 server. I was able to upgrade to fc5 server. Finally, I decided to give a shot at it. Now, I get an error when it boots up. I have backed up all my data already. Anyone can help me find a solution if possible. Your help is appreciated.

kernel panic - not syncing: attempted to kill init!
thanks in advance
