Also, if your kernel is compiled with dynamic debug try this:echo "func dtv_property_process_set +p" > /sys/kernel/debug/dynamic_debug/controlecho "func dvb_frontend_handle_ioctl +p" > /sys/kernel/debug/dynamic_debug/controlThen tune a channel and paste the kernel log here.(use something like: "dmesg | grep DTV_CLEAR -A10 -B10").
