I was looking at top the other day and I noticed that my cpu is spending a lot of its time (~60%) on a process "kdvb-ad-*-fe-0 where * can be 0, 1, 2 or 3, presumably for any one of my four dvb cards.
Code:

The process is running even when the frontend is doing nothing and even if I shutdown the frontend. Shutting down the backend will stop the process.

Is this normal?
