Well, this doesn't work. If i did tune a channel before or used the dvb card
somehow for watching tv, unloading and reloading the cx23885
module also makes the card unuseable.
In dmesg there's lots of "do_IRQ: 1.161 No irq handler for vector (irq -1)"
messages then. This can only be fixed by rebooting the computer.
