Yes, there was a third one on shutdown.

My beaglebone xm won't do idle:

| omap3_pm_off_mode_enable: Core OFF disabled due to errata i583

but it would if it could, right? That means that I can't test the wake

So I will try to fix the tx-pm, fold patches and then prepare another
And I could verify that DMA works on that omap3 :)
