Hi All, after a lot of test, I discovered a module (more than one) that makes redhat-config-network going in SEGFAULT; Those modules are: usbnet (makes my Pc2Pc usb modem working...but i don't use it) and usb-controller. Removing usbnet module I can make Network Configuration (gnome) application works; removing also usb-controller (renamed in usb-uhci) the Internet Configuration wizard works too. How can I prevent those modules from loading ? However, removing usb-uhci my Ps/2 (OEM Logitech optical) mouse doesn't work anymore. Thanks. Igor. ______________________________________________________________________ Yahoo!
