This my first (but not least :) ) message on that mailing list. I hope I will find my solution.
Here is my problem:

I have a MPC8272ADS board, 64MB RAM, 8MB Flash.
I compiled u-boot using the existing config file, and compiled my linux kernel successfully with the defconfig file too.

I have updated u-boot, downloaded my kernel file, and a ramdisk image from the eldk distribution.
I have tried using a lot of bootargs (
bootargs root=/dev/ram rw console=ttyS0,115200

When I am resetting my card, it reboots:
