These are successfully generated 1711 during firmware loading, and after that wavefront_status() 1712 reports that an interrupt is pending on the card from time 1713 to time, but it never seems to be delivered to this 1714 driver. Note also that wavefront_status() continues to 1715 report that RX interrupts are enabled, suggesting that I 1716 didn't goof up and disable them by mistake. 1717 1718 Thus, I stepped back to a prior version of 1719 wavefront_wait(), the only place where this really 1720 matters.
