I get a repeatable crash immediately on 017 with these changes.  Same
machine as before (1GB/Dual P3-Xeon), just a slightly different partiton
layout.  Was I supposed to avoid test 017 too?

Traces / disasm attached.  Going to recompile w/o highmem now, will let
you know if it fails.  Hmm, same thing happens, and same w/o highmem on
non-SMP.
