It's not a bug, it's a feature. Because the frontends have
significant power requirements (and hence get very hot), they
are powered down if they are unused (i.e. if the frontend device
- is closed). The dvb-core.o module paramter "dvb_shutdown_timeout"
+ is closed). The dvb-core.o module parameter "dvb_shutdown_timeout"
allow you to change the timeout (default 5 seconds). Setting the
timeout to 0 disables the timeout feature.
