since kernel 4.5.3 a severe bug has been introduced with commit 2c1f6951a8a82e6de0d82b1158b5e493fc6c54ab ( [media] videobuf2-v4l2: Verify planes array in buffer dequeueing ),
a system freeze will occur with TV cards ( DVB-T ), for example with "leadtek winfast DTV1000T", "leadtek winfast DTV1800H", "Avermedia" and many others,
