Oops on 2.6.31.12-rt21

[Yogesh Chaudhari]

Hello,
          I installed the 2.6.31.12-rt21 kernel on Intel Core i5
machine with Ubuntu installed. I am getting the following oops message
on boot-up after which the machine hangs up. This error does not come
up on the vanilla kernel.

Kernel panic - not syncing: Attempted to kill init!
Pid: 1, comm: swapper Tainted: G      D    2.6.31.12-rt21 #1
