Dear again sirs,

After some investigation I've found 2 new clues.

1 - The problem begins always with a small signal drop. It usually lasts 
only a few seconds but that's enough to crash the adapter connected to 
the antenna.
2 - Now the news: if noticed that when this happens, the driver's kernel 
module belonging to that same adapter just dies, as you can see in the 
ps output below with my adapter /dev/dvb/adapter9:

The adapter's device files /dev/dvb/adapterX are kept in their place, 
but they are no longer readable nor writeable.
My question is: which module is the responsible for launching the kernel 
processes [cx88[XX] dvb]? Is there some way of manually launching one of 
them?
How can I restore the crashed device without needing to restart the 
machine or even remove the driver and affect the remaining working adapters?

Thank you very much for your help and time.

Kind regards.
