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.

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.

Try making this change:
