In case anyone else out there is having this problem, I finally managed
to track down the cause of the errors. It seems that there was a
conflict with the videodev.ko module - there is one included in the
stock Fedora kernel, but for some reason there's also one included in
the video4linux-kmdl-xxx package from atrpms. Uninstalling the
video4linux-kmdl-xxx RPM seemed to fix everything and now it all works.

Sorry, I can't help you. It looks to be some kernel bug you're
triggering. As far as I can tell it has nothing do to with the driver.

No, I doubt it's a memory issue as I've got 1GB and there's always
plenty free. Besides, it works with 2157_FC5, so it seems weird that
it doesn't with 2174_FC5.

Haven't seen this one before. It's not a driver issue, but seems to
be kernel related. Could it be that you don't have a lot of memory
available? Perhaps low memory conditions cause problems here (I'm
purely guessing here)

Having looked at the problems I've been having getting the ivtv
driver to load on the latest FC5 kernel, I've deduced that it's
hiccuping during a firmware load (see below dmesg output). Th
offending line, I believe, is

paging request at virtual address 76747729
Has anyone seen, and managed to fix this?
