I know that i have seen such messages before the upgrade. I have another asterisk server which is bristuffed, and there i can see this message with 'dmesg'. I am absolutly positive that DAHDI was not built with NO_ECHOCAN_DISABLE, since i have only downloaded the package and done a 'make; make install' without touching anything of the source code. By the way, i am using DAHDI-linux 2.1.0.3.
