I get oopses like this rather often on my rpi2. As can be seen it has quite a bit of USB devices attached and the odd thing is that if I disconnect either of the tv-capture devices the oopses are gone. Any ideas what triggers it? I'd be ahppy to try any patches. The call stack differs between the oopses (some triggered by network writes, some by dvb reads etc), so I suspect its something to do with the guts of the usb host driver (and load related).
