in your config .... what is your LMI.....(autosence)
have you set the encapsulation command on the int`s see this link http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121cgcr/wan_c/wcdfrely.htm#xtocid221854 input errors usually mean that there is some kind of encap error...(int doesn`t understand the packet/frame it`s recieving)....
