One can change number of kernel stack pages for i386 and amd64 platforms by means of /boot/loader.conf without need to rebuild a kernel using kern.kstack_pages tunnable. It equals to 2 for i386 and to 4 for amd64 by default but I change it from 2 to 4 for my i386 systems running IPSEC tunnels and/or wifi due to these subsystems being stack-greedy.
