Hi John-Mark,

> This is w/ a resonably recent current i386 kernel (r275062)

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

>...  Any suggestions?

> uart0: <16550 or compatible> port 0x3f8-0x3ff irq 4 on acpi0
...
> uart0: <16550 or compatible> port 0x3f8-0x3ff irq 4 flags 0x10 on acpi0
> uart0: console (9600,n,8,1)

  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.
