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
via UART on this one?
So I will try to fix the tx-pm, fold patches and then prepare another
batch.
And I could verify that DMA works on that omap3 :)
