This bug has been in earlier kernels as well. I've also seen it reported for Debian and Gentoo. Could be an upstream bug ?
There is also a suggested fix lying about on the internet, specifically http://www.devbase.at/voip/yeaphone.php Quote: as you have noticed the development of the yealink kernel module has more or less been stopped. Some time ago I published a patch to get rid of the infamous 0xfd response (see yealink.patch at https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2214) but Henk (the original developer) does not seem to have the time for maintenance or development any more. -- During Boot Get nk.c:unexpected responsefd/build/buildd/linux-source-2.6.22-2.6.22/driver/input/misc/yeali Keeps repeating this with no end to the repeat.
