Anyhow, rmmod will not remove a module in use, rmmod -w will wait untill it can be removed (which, unfortunately will not happen in your case). Finally, you have rmmod -f (which requires CONFIG_MODULE_FORCE_UNLOAD during the build, hence 'Forced module unloading'). Do note that forcing out a module can be quite hazardous.. :-) -- Henrik -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
