Hardware echo canceller not loading

Hello!

I’ve got a TE122 card with echo canceller installed.

dahdi_scan output:

This is my system.conf:

I’m not sure, if the echo canceller is active because my dmesg log is full of this:

…

…

Did I configure something wrong?

I also checked my boot log and found this:

Does anybody know if the echo cancelling is now active, besides the recurring error messages in dmesg?

hi:
please check the modules.conf file, MG2 is there! remove that or set it to none.
