Perhaps I don't have the right debugging options turned on, but I'm 
getting a page fault at that same spot (mounting root) with kernels built 
on source from about fifteen minutes ago.
Kernels built from source from June 26 work.

I've tried different kernel options trying to find something that doesn't 
crash, but no luck so far.
