Icecube/lite5200 board does not boot in linux-2.6.25.x

Hi
I am trying to boot Freescale Icecube/Lite5200 board using
Linux-2.6.25.x,
but nothing gets printed on to the serial console after the
uncompressing kernel and ramdisk messages.

The same board boots up cleanly with Linux-2.6.24.7. 
But anything after linux-2.6.25 does not work at all. 
I am using ELDK-4.1 as my toolchain.

Using BDI2000 device I dumped the '__log_buf' section
to find out whether there is any activity that goes behind the scene
and found out that the system crashes with below log messages.

Sorry for the huge log pasted below. 
Is there something much different in 2.6.25 from 2.6.24.7 that makes
this to fail?

Any help would be hugely appreciated

Thanks
Biswa

There is a known bug in 2.6.25 which has been fixed in the stable tree
(2.6.25.3).  It might be your problem.
