I don't believe it's the x-driver. It is more likely to be the ivtv osd driver.
The top bottom half thing comes from the x driver splitting large updates into 2. So the 1st one has worked and the second on failed for some reason. Turn full ivtv logging on and send me your messages file at the point it fails if you like. The most likely cause is that there is a loop where the osd code tries to gain access to the dma engine and waits until it can get access. This can block indefinitely if something goes wrong and the x server is blocked in the ioctl waiting for it to happen. Maybe we should return from this loop after a short time (1 minute or so) with a failure since something has gone horribly wrong when that happens. There is debugging for this happening something like Reg Status ....... But the decoder debugging needs to be on to show it.
