I've got a custom 852T board, similar to an AdderII.
I've got the board booting linux fine using NFS. Now
I'm trying to get it to work stand-alone, and I can't
get it to boot from a RAM disk. I'm using the 2.4.25
kernel from Denx, and the Ramdisk image from the ELDK
(ppc_8xx/images/ramdisk.image.gz).
Below is the output I'm getting. The "MAJ" tags
indicate printk's that were inserted by me. If anyone
has a clue to what I'm doing wrong, I'd appreciate it.
Thanks,
