This is correct.

Hmm, don't know why init would get a segmentation violation here.  If you
didn't already, compile init with -g and look where the offending address in
the code is and how it got there.  Depending on your implementation of DDB
you might also want to set a breakpoint at vm_fault and look why it doesn't
want to give init access to the page at 67000.

This is to be expected after the above.
