I've seen this effect elsewhere. Not exactly the same, but it's been 
happening with me on some systems since 11.1. The context I see it is 
when spinning up a bhyve instance in screen. I see a bit more than just 
booting, something like "unreferenced ps/2 interrupt" after "Booting...".

The bhyve instance itself is fully functional. Logging into the bhyve 
instance through ssh I can see its dmesg and it all looks OK. However, 
if in syslogd.conf I enable console logging via console.log and reboot, 
*nothing gets written to it*.

Have had this issue for about a year now, not been able to fix it. 
Frustratingly, it doesn't happen with all VMs. I've not seen it happen 
with a 12-current VM, just 11-stable. And even then, not *all* 11-stable 
VMs.
