I bisected the issue down to: arm: omap4: support pmu - 4fefbe94a77c3d3b5e75d386628c36298c72c57f
However, after reverting that patch against linaro-2.6.39, it then hangs a bit later after:

So this second hang seems to be config related (I suspect something dropped out in the bisection). After going back to my original config the system boots fine after reverting the pmu patch.
Looping in Avik Sil who confirmed that PMU was working fine after I merged that patch. Avik: could you provide us with the config you used?
Please find attached the config I used.
