My guess is that the error cause is rather simple; the initial address space layout
is mashed.  My experience shows that porting NetBSD/arm is as easy as to
complete initarm(); no change necessary for other parts.  Most errors come from
the lack of understanding about they way how the target ARM SoC address layout is 
adapted for NetBSD, in particular, where RAM paddr resides and where DEV registers
are vaddr'ed.

It's pretty normal.  Kernel is trying there to craft virtual address space for the very
first user process.
