Please describe freeze:
1. irrecoverably hang the machine?
2. logs an Oops in dmesg or /var/log/messages, but the other core still
runs if it a dual core Atom?
3. cat just hangs but can be killed?
You can of course load the ivtv module with the debug option set. As
# modprobe -r ivtv
# modinfo ivtv
# modprobe ivtv debug=0xblah
Where blah is an OR'ed combination of debug flags as shown by modinfo
If things are just hanging and not freezing the machine, then odds are
you might not be getting IRQs. Does the output of cat /proc/interrupts
show a growing interrupt count beside the ivtv interrupt when you try
and cat /dev/video0?
