As you said, This arrived after updating from 9.04 to 9.10. I´ve recompiled the sources after patching it and no erros during compilation
I don´t know why the system freezes.
I know that from Linux kernel 2.6.31 the old net_device structure used in interceptor.c is unsupported.
may be any bug implementing the new net_device_ops sctructure on the patch
May be the Language Spanish es-ES ? I don´t think so cause in previous version works well.
I don´ know the reasson why sorry.
Someone can help please?
