That's not a "crash".  The default DDB configuration is to enter the
debugger when it sees BREAK on the console serial line.  Cheap serial
hardware often sends a BREAK when you turn it off, unfortunately; real
terminals generally don't.

You can use sysctl to change the value of hw.cnmagic to something other
than BREAK to avoid this problem.
