I just got a brand new 720 and attempted to boot linux-2.6.11-rc2-mm2
(which is the current base for hotplug memory work) with the default
configuration.  Only got as far as ...

I looked through the January and February list archives but
couldn't find anything similar.  Anyone know what this might be,
before I start some investigation?

No problem booting the linux-2.6.11-rc2 kernel, but I experience
the above situation after applying the -mm2 patch.
