Your smoking gun just set itself on fire and burnt to death in a test run: (2) smkelly@edgemaster:~$ cat /boot/loader.conf ... # Network #miibus_load="YES" if_xl_load="YES" # 3Com 3c900B-TPO if_dc_load="YES" # NetGear FA310TX if_ppp_load="YES" # PPP ... Yet, it still comes up with if_dc.ko loaded and no if_xl.ko. On another similar note, a few minutes ago I realized that the snd_emu10k1.ko module wasn't loading because: Preloaded elf module "snd_emu10k1.ko" at 0xc037f544. link_elf: symbol sndbuf_getbps undefined So, after the system was up I figured I'd try to reload it. I figured I needed snd_pcm.ko or something, so I kldload'd it and locked my system solid. On the reboot after that, I went back to the 'ok' prompt in loader, and decided to try 'load /modules/snd.ko'. It registered 5342532 different sound modules (all of them I think), yet doing 'lsmod' in loader showed NONE of them except the snd_emu10k1.ko from my loader.conf. Upon boot, none of them were there. So, what happened to my 'load /modules/snd.ko'? -- Sean Kelly | PGP KeyID: 77042C7B smkelly@zombie.org | http://www.zombie.org For PGP key, send e-mail with subject "send pgp key" To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
