Will not help.  This is a trap in x86 pmap, the locking error is just a
side effect, not an issue in UVM.  Quite certainly it is a problem with
i386 PAE, so port-i386@ is a better place to ask.  If NetBSD ships PAE,
we ought to fix its bugs, but generally - i386 PAE is inferior to amd64
in practically all aspects, so just do not use it if you can.
