I think you are correct and that this is your problem.  If you have 
dahdi-tools 2.2.0 installed, but using and older version of dahdi-linux, 
you will get these errors since the format of some of the ioctls have 
changed. (related to https://issues.asterisk.org/view.php?id=14499)

How did you install dahdi-linux?
