MontaVista 4.0.1 on Xilinx ML405 board

[gsk19 at bezeqint.net]

We built a design for ML405 using EDK 9.1.02. EDK also 
creates linux drivers for MontaVista Pro 4.0.1 (2.6.10).
The drivers were copied to a clean copy of Pro 4.0.1 and the 
kernel was built. When we downloaded the kernel to the target 
and ran it, we got exception. We didn't get any messages on 
the hyper terminal. 
We used Tri-Mode Ethernet and UART lite.
MontaVista checked the integration of EDK 8.2 with ML403. 
Can you help ?
