It *sounds* like the card needs some time to stabilize.
You could try using a script (called from /etc/rc.local ) which will
remmod the ivtv driver, and then insmod it back. That should trigger
the udev subsystem.
(Althernatively, there is a script which re-triggers udev, which should
then recognize the cards.
Have you tested putting these 2 cards into different slots? Or just in
the other slot?
Have you tested with just one of them installed? And then the other?
In both slots?
There could be some sort of interrupt contention going on which a
slot-swop would fix, obviating any software work-arounds.
Please let me know if anything I say offends you.
I may wish to offend you again in the future.
