It's good to have that confirmed. :-) I am not sure I can really confirm that, it was more the suggestion of pci_alloc_consistent that looked very wrong. I only did a quick check in ivtv-queue.c and most of the stuff looks in order. But since I don't really know the real flow of data it is hard to say for sure. But given that the driver works for me it must be correct. :>
