You must unload all the modules depending on sound.ko before it will unload. At that point, I believe I've seen it unload itself. Same with netgraph.ko, and the modules that require it (ng_*.ko). -- Fuzzy love, -CyberLeo Technical Administrator CyberLeo.Net Webhosting http://www.CyberLeo.Net Furry Peace! - http://.fur.com/peace/ ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
