Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 8bit Sender: linux-media-owner@vger.kernel.org List-ID: 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: root@*********:/home/*****# ps aux | grep cx88 root 903 0.0 0.0 0 0 ?

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.
