I'd be willing to bet this is the dbdma bug Iain mentioned. Like the dma

It sounds exactly like the bmac bug.  So changing pmac_awacs_tx_intr()
from

	while (write_sq.active > 0) {
		...
		if ((stat & ACTIVE) == 0)
			break;	/* this frame is still going */
		...
	}

to

	while (write_sq.active > 0) {
		...
		if ((stat & ACTIVE) == 0) {
			if (cp == bus_to_virt(in_le32(&awacs_txdma->cmdptr)))
				break;
		}
		...
	}

fixes it or something?
