Changing a line in the function dcons_modevent() (File
sys/dev/dcons/dcons.c or dcons_os.c depending on your sources) should
help you.
#if __FreeBSD_version >= 500000
- if (ret == 0) {
+ if (ret == 0 && dcons_consdev.cn_pri == CN_DEAD) {
dcons_cnprobe(&dcons_consdev);
dcons_cninit(&dcons_consdev);
cnadd(&dcons_consdev);
}
#endif
As a work around you should also be able to set
boot_multicons="YES"
in your /boot/loader.conf file. (Not tested)
On a running system you can use conscontrol to change console devices.
