 It is not a panic, but a BREAK on the serial console which invokes
 ddb(4).
 
 You can avoid it easily by adding a setting for hw.cnmagic to
 /etc/sysctl.conf, see cnmagic(9) for an explanation:
 
              as the global magic sequence.  The escape sequence is character
              value 0x27 and can be used to encode special values:
 
                    0x27   The literal value 0x27.
                    0x01   Serial BREAK sequence.
                    0x02   Nul character.
