PPC403 bootup problem

[Tom Shaver]

I am trying to boot my IBM 403 eval board using Grant's 403 kernels. First
question is, I don't know what eval bord it is. It doesn't say "OAK" or
anything like that on it. 2nd, the board came with a 403GA processor, in a
socket, which we have replaced with a 403GCX. The ROM monitor eprom routines
startup fine with the GCX installed, recognizing the processor and speed
correctly. It goes through what looks like a normal startup, does a bootp,
loads the linux kernel via tftp, tries to boot the kernel, and hangs
immediately. Here's the transcript of what happens (from the serial port).
Any input appreciated.
