Hi John-Mark,

  I verified the r274463 i386 snapshot boots fine. That's not quite as 
recent, but:

  The "flags 0x10" text isn't being displayed in the i386 dmesg. This is 
derived from /boot/device.hints i.e.

...
hint.uart.0.flags=0x10
...

  You can see this from bhyveload by issuing a 'show' command to dump 
all the environment, including what was read in from device.hints by the 
loader, or "more /boot/device.hints".

  It may be possible that this file isn't being populated in your image, 
or being read in by bhyveload.

later,

Peter.
