Reply-To: Shawn Jin List-Id: Linux on Embedded PowerPC Developers Mail List List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Hi, I'm trying to load a kernel image for Ebony built with the default configuration ebony_defconfig from 2.6.10. The image is in u-boot format. The root filesystem is set to a remote NFS root. Strangely I found the ethernet driver cannot detect the mac address. The address is supposed to be transferred from bd_info struct, isn't it? Also I noticed that the kernel command line shown is not what I defined on u-boot's bootargs. Are there some changes that I'm not aware of on kernel handling command line? Below is the kernel dumped message. => bootm 200000 ## Booting image at 00200000 ...
