As previously requested.

The following is the behaviour of the latest mainline kernel on the LDP3430
platform.

<spontaneous reboot>

My guess is it's the watchdog which hwmod apparantly can't deal with.
Note also LDP framebuffer doesn't appear to work in this configuration:

CONFIG_OMAP2_VRFB=y
CONFIG_OMAP2_DSS=y
CONFIG_OMAP2_VRAM_SIZE=2

CONFIG_FB_OMAP2_NUM_FBS=3

#
# OMAP2/3 Display Device Drivers
#
CONFIG_PANEL_GENERIC=y
CONFIG_PANEL_SHARP_LS037V7DW01=m

With the FB_OMAP driver, it looks like the screen isn't being correctly
driven - the openhand logo appears in outline with green splodges in
places (but unfortunately, because of the reboot, it doesn't stay there
for long enough to get a photo of it.)

Full boot messages below (with FB_OMAP2):
