saa7146_wait_for_debi_done_sleep timed out
Subsystems (2)
Hello,
After updating the kernel to 3.14.15 I am seeing these messages:

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...
PATCH 1/1 Turn bothersome error into a debug message
Once again...

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.

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