I figured... :-)

I've copied GENERIC.MP to a custom config and added:
makeoptions     COPTS="-O2 -fno-omit-frame-pointer"
options         DDB             # in-kernel debugger
options         DDB_HISTORY_SIZE=512    # enable history editing in DDB
makeoptions     DEBUG="-g"      # compile full symbol table
options         DIAGNOSTIC      # expensive kernel consistency checks
options         DEBUG           # expensive debugging checks/support
options         LOCKDEBUG

I'll reboot with that and work on reproduction.  It'll take a little
while.
