Or it could be that with omap_hdq.c no longer blocking SoC
deeper idle states, omap_hdq.c now loses context if you have
omap3 off mode enabled during idle?
If so, this can easily be fixed by adding a cpu_pm notifier
along the lines of what we already have for few drivers:
$ git grep -e CLUSTER_PM_ENTER -e CLUSTER_PM_EXIT

Tony
