It's a bit messy... a) The patch I bisected to is not the root cause of the bug; it just triggers a ~9 year old bug in the v4l code - so this patch isn't going to get changed.
b) The ~9 year old bug is in a particularly hairy piece of memory management code in v4l that I doubt anyone is going to fix. c) The plan is all the drivers using that API are to either be retired or rewritten using a new API; that's already been done for some of the drivers and the bttv one is a few months out. I'm not sure that's any use to this version of Debian though. d) The work arounds are: 1) Disable iommu 2) some v4l tools can use an mmap interface rather than the read(2) interface; that seems to be OK.
