I have the same problem. If I turn off the display then the board boots.

Thanks to John Stultz for making the connection that the hang was just as the display gets set up on a successful boot.
Kernel config and boot logs are attached to the bug.
There are a couple of config options at least that deceptively offer things which only break boot.
Since there's no relationship between configs people are using and the one Panda stuff is getting heavily tested on (arch/arm/configs/omap4_defconfig on Seb's and my tree), I am thinking we should maybe take an assertive approach about it -->

If CONFIG_OMAP_RESET_CLOCKS=y is breaking boot, it's because there is a broken driver someplace that is not requesting its clock(s). That driver should be found and fixed.
Disabling this option is only hiding a broken driver, and as an additional side effect, will almost surely prevent the device from hitting low power states in idle and suspend.
