slaballocation panic on boot

I would like to bring good news but unfortunately that is not the case.  I have
updated to sources with todays (9/25) fixes.  The machine running 4.8-p10 is
rebooted into the dragonfly kernel so make installworld can be performed.  
'make installworld 2>&1 | tee /devel/dragonfly/buildlog/installworld.log' does
not get written, but on the console only the first shell script 'for _x in [
cp....' is printed.  The system always fails here.  Sometimes with ddb,
sometimes without.  The panics I have seen have been double faults.  The core
dumps I have collected yield useless information (see attached).

kernel config is attacted (no slaballoc, no memap)
useless crashdump attached
