Hmmm. I know initrd works because I use it quite often. All of the
memory relocation looks OK. Cort had a good suggestion, can you
build a kernel that boots using NFS (or at least boots to the point of
trying to mount the root fs).

This looks a little weird. It should not be necessary and I
don't know what happens when it is used.

Look for 'log_buf' in your System.map. It will have an address
something like 'c00daa78'. When you reset the MBX, use the
EPPC-Bug to dump the memory starting at daa78 (in this example).
This is the text of the kernel printk until the serial device is
initialized. It may hold some clues.
You could also use 'noinitrd' on the command line to determine
if the problem is related to initrd or something else.

That should work fine.

They always are :-). One wrong bit can screw up everything......
and you have a 50% change of getting it right :-).
