[ELDK] Linux hangs

Hello,

I've been trying to port linux to a PPC440GP based board. I am using ebony's files as a starting point. However, linux hangs after the image is decompressed. I get a different log after the first try, and the same logs after that. It seems like the kernel gets confused. Here is the __log_buf and my dts file.
