 I added some more assertions in an attempt to assist in narrowing this
 down.
 
 Can someone with sh3 hardware please update and try to reproduce the
 bug again, and share
 
 (a) the text of the panic and stack trace,
 (b) the output of `ident netbsd | grep uvm_map.c', and
 (c) if you can get it, the output of `show map <mapaddr>' in ddb?
 
 (The trouble with the last one, at
 <https://gist.github.com/rokuyama/b812a0f27c0354f6fc5f67c0c0be2929>,
 is that I don't know what revision of uvm_map.c was being used, so I
 don't know what the line number refers to.  And it would likely really
 help to see what's in the vm map so I can trace how the search
 algorithm ran.)
