[BUG] PandaBoard hangs before starting init while booting v3.12

I'm having difficulty getting a PandaBoard ES rev. B1 to boot v3.12 and
linux-next (30121118). I'm booting with a brand new u-boot
(c2e5e802ecb7ab668ce9911b210ed68c804b349f).
In both cases the device appears to hang shortly before one would expect
init to start as seen in the boot output below. I'm booting with the
omap4-panda-es devicetree. As far as I can tell, the machine is
completely dead and will not respond to even sysrq. I have a PandaBoard
A4 which apparently has no trouble with the same kernel image.
The only issues I can see in the output are,
* pinctrl issues pertaining to wl12xx[1], these shouldn't cause the
machine not to boot
* Various missing vmmc regulators
* hw-breakpoint issues:
* Failed to enable monitor mode on CPU 0
* CPU 0 failed to disable vector catch
These sound serious and occur near the hang. Perhaps this is the culprit?
Any help would be greatly appreciated.
Cheers,
- Ben
