Hello,

I want to run Linux on ixdp425 board. This board has redboot bootloader. I'm using buildroot version 2009.08 and want to run kernel 2.6.30, and run rootfs from ramdisk. I managed to boot the kernel but it stops before it's able to load the rootfs. I've attached the boot log below. Does anyone know what is next thing the kernel is supposed to do or what is wrong here? 

Any help is greatly appreciated. Thanks and happy holidays.

Regards,
JA.
