I believe superpages were mfc'd to -stable as well.   I have one machine 
that faults in gcc with this turned on.   You can try adding 

vm.pmap.pg_ps_enabled="0"

to /boot/loader.conf, rebooting and see if that fixes the problem.  If so,  
you might provide the list with your hardware configuration.
