This means the clocks are not enabled at that point.

If you comment out postcore_initcall_sync(omap3_l3_init);
in drivers/bus/omap_l3_smx.c you'll see the proper stack
trace instead of the l3 interrupt trace. The system will
hang at that point most likely.

Hmm not much has changed since v4.9. Are you sure you
had v4.9 or some earlier v4.9-rc version?
