Me too.  Like J.Catrysse@, I have a Supermicro X9 ipmi at 115200 with console
forwarding set in the BIOS on fbsd 11.1.  In addition, I have loader.conf
configured for dual consoles (serial/ttyu0 and KVM), as in:
hint.sio.0.flags="0x30"
boot_multicons="YES"
boot_serial="YES"
comconsole_speed="115200"
console="comconsole,vidconsole"

only one syslog line logging to /dev/console:
kern.*;syslog.err                                       /dev/console

ktrace syslogd & kill -1 it (or restart it), reveals:
 37969 syslogd  GIO   fd 10 read 1409 bytes     XXX syslog.conf
      ......
 37969 syslogd  CALL  openat(AT_FDCWD,0x7fffffffc4d6,0x9<O_WRONLY|O_APPEND>)

 37969 syslogd  NAMI  "/dev/console"
 37969 syslogd  RET   openat 12/0xc
 37969 syslogd  CALL  writev(0xc,0x7fffffffaa10,0x7)
 37969 syslogd  GIO   fd 12 wrote 65 bytes
       "Sep 28 17:18:59  syslogd: /dev/console: Interrupted system call\r
       "


This is a recent upgrade to 11.1, but it worked in 10.3.
