Hummingboard boot hangs in -HEAD

[Tom Sparks]

I'd initially thought that it was my build that had failed so I snagged an
image from ftp.freebsd.org and no, that image fails to boot to multiuser as
well.


Here's where it hangs:
--- snip ---
usbus0: 480Mbps High Speed USB v2.0
usbus1: 480Mbps High Speed USB v2.0
ugen1.1: <Freescale> at usbus1
uhub0: <Freescale EHCI root HUB, class 9/0, rev 2.00/1.00, addr 1> on usbus1
ugen0.1: <Freescale> at usbus0
uhub1: <Freescale EHCI root HUB, class 9/0, rev 2.00/1.00, addr 1> on usbus0
hdmi0: i2c transfer failed: 2
fb0: failed to get EDID info from HDMI framer
fbd0 on fb0
VT: initialize with new VT driver "fb".
uhub0: 1 port with 1 removable, self powered
--- snip ---

with boot -v I get a bit further:
--- snip ---
VT: initialize with new VT driver "fb".
random: harvesting attach, 8 bytes (4 bits) from fbd0
uhub0: 1 port with 1 removable, self powered
random: harvesting attach, 8 bytes (4 bits) from uhub0
--- snip ---

Then a while later, some other stuff appears:

--- snip ---
uhub0: 1 port with 1 removable, self powered
random: harvesting attach, 8 bytes (4 bits) from uhub0
sdhci_imx0-slot0: Divider 250 for freq 400000 (base 200000000)
mmc0: Probing bus
uhub1: 1 port with 1 removable, self powered
random: harvesting attach, 8 bytes (4 bits) from uhub1
--- snip ---

Supposition is that this broke in the range of r295351 through r29554.

Anyone?
