Hello MarvS, In fact i've tried this .deb yes, but also to compile the modules from the tar.gz (http://linmodems.technion.ac.il/packages/ltmodem/11c11040/agrsm-11c11040-2.1.80~20091225.tar.bz2), i even tried the dkms one, and many others.. I always got the same null pointer dereference problem, i'm going to try your unloading script and report back. Thanks!
