I did not make myself clear.

All modules are in place and working  - *if* I "modprobe" them manually.

The problem is "service dahdi start" does not load echo+dahdi_echocan_oslec.

I have a production system that does it. I just do not know how.

After copying this system to another machine and upgrade it (apt-get
dist-upgrade), echo+dahdi_echocan_oslec does not get inserted anymore and I am
wondering why.

I intend to upgrade the production system tomorrow night and this "bug" is
haunting me.
