Unable to boot linux on Xilinx ML403 board

[Mohan Krishna T]

Hi all,
            I am working on Xilinx ML403 board. I am trying to boot with
Linux 2.4. My hardware includes a UART16550 and EMAC (OPB Ethernet) in
scatter gather mode. When I boot the linux. It is coming up to the following
point and hanging indefinitely. I have pasted my booting sequence below:
