[tran vanle]

Hi every one

I had used kernel of ELDK 3.1.1 and Ramdisk of ELDK 4.0 on board MPC8xxL .It run ok but I see it will meet trouble :D
When I use kernel and Ramdisk of ELDK 3.1.1 for MPC8xxL (I only rebuild Kernel use oldconfig and use uRamdisk in source (not rebuild )) but I receive error
