I have a Yun hiding, unused, in the bottom of a drawer somwhere. I had not realized a Tian also had a Linux side.
The Yun was a good idea ruined by the way it was implemented. Making an even more complex version was probably stretching the Arduino folks too far 
I still have no idea what the OP's Linux messages mean but the fact that they might be relevant just makes the debugging even more complex.
