You can't lower the securelevel once it's raised. There is a way, if you
have compiled DDB in the kernel, but you have to be on the system console,
and stop the running kernel with CTRL+ALT+ESC.
The only way you can lower the securelevel on a machine that you don't have
consle access *and* DDB compiled into the kernel is by tweaking the proper
lines in /etc/rc.conf and rebooting.
