It has been a while, but I think I had a similar error with ivtv that 
could be fixed by passing "swiotlb=force" to the kernel (extra in the 
configs).  This was with an unstable changeset in between 3.0.1 and 
3.0.2.  When I changed over to 3.0.2 I believe it then started to panic 
with the setting, but booted fine without.  Since I've been busy trying 
to get a FreeBSD domU to work and have it not panic every two seconds, I 
have yet to look into it further.  Additionally when using that setting 
I could capture video initially, but after some time it would lock up.  
I don't know if that issue was related.   Anyways it would seem as if 
something affecting the issue was changed in or around 3.0.2--assuming 
my memory is even partially correct.  That setting may still be worth a 
try, though, if you do not want to try upgrading.

Sorry for the continuous stream of guessing and I thinks---Hopefully it 
helps,
