Hello,
After updating the kernel to 3.14.15 I am seeing these messages:

filling up the logs(one about every 5 seconds).
The TV card is a Terratec Cinergy 1200 DVBS (I believe.. it's rather old).
I can not observe any erratic behavior, just those pesky messages...
I see there was an earlier post here in 2008 about a similar
problem...(Cinergy 1200 DVB-C... a coincidence?)
What does it mean?
Do I need to be worried?
I am using a debian testing on a 32 bit box.
The previous kernel was linux-image-3.12-1-486.
It did not show those messages, but maybe due to some configure
options... I built this one from linux-source-3.14...

Answering my own question:
Other posts suggests that it is not actually an error on cards without a
CI interface. Here's a patch that turns it into a debug message, so it
does not clobber the logs.

Let's see if that works now...

Hi Johann,
I've added this to my todo list and will look at this soon (next Friday or Monday
most likely).
