"explanation": "1128960 drain(s) found the read slot exhausted while another slot held unread data, and 70 no-IRQ refill(s) landed off the read slot. That is the regression: a multi-sector DMA stalls because its continuation was filed in a slot nothing announces. The fix is that the no-IRQ refill must advance the read pointer -- it is a continuation of the drain already in progress, not a new notification."
