That is what I thought you might say. I have been digging around in the code, trying to figure out the answer to that question myself. For some reason, even though that patch worked, it just didn't 'feel' right. I was looking for someone to confirm that there was a bigger problem to search for. Now I'll go back and hunt down the bigger beast and find out why that hwif->mate is coming out null.
