[U-Boot-Users] Linux on IXDP425

I have U-boot compiled for IXDP425 (version 1.1.6) I am trying to use it to load MontaVista kernel 2.6.10 on this board. U-boot get to the stage where it says "Starting Linux kernel" and the board hangs up. Following is the log of U-boot output. I hope someone on this list have experience with this.
The uImage was built from zImage, we tried building it from other compiled images but got the same error.
