Hi Paul,
   Appreciate the feed back. My responses are in line below..

*I am not using old device tree. I created one which is based on mpc834x_mds.dts in 3.4.36 kernel. Attaching it for your ref..*
When I use this newly created one with 2.6.32 kernel it works fine. Hence I mentioned I was using the same device tree for both kernels!!

-rw-rw-r--  1 platform33 platform33 4055829 Dec 19 14:21 uImage4hd12_3x
-rw-r--r-- 1 platform33 platform33  1653704 Dec 13 13:30 uImage4hd12_2x
Is it this size diff causing this issue ??
Any idea what may be the reason for increase in 2.5 MB ???

I tried using a dts with just serial ports and that failed too!!

I tried enabling CONFIG_MPC834x_MDS=y in .config but I still have the 
same error
