Ebony/440GP progress update.
I'm almost there ... I can smell it, I can taste it, I can hear it .... but
I just can't see or feel it yet.
Wolfgang mentioned this in a previous post. As everyone knows, appropriate
bootargs need to be passed for the kernel to boot with an nfs-mounted root
filesystem. I've triple checked everything and am 99.9999% sure I'm setting
the bootargs appropriately. For some reason, whenever I try booting, the
'Kernel command line:' always says 'ip=on'. I searched the archives and
couldn't anyone that had a similar problem.
I 'll attach my boot log with a printout of my u-boot env vars along the
way:
