This was causing the miibus module to load, even though miibus support was compiled in the kernel. After removing this line, the system will work OK with the probe line back in. This is probably not correct behavior, even though I *did* have a mistake in my loader.conf file. However, removing the line fixed the problem. I was playing around some months ago trying to get the system to recognize the 3X920 card builit in to the docking statiion. I apparently first tried to load the if_xl.ko module and then tried compiling it in to the kernel, but forgot to remove the line from loader.conf. Interesting that it worked OK with 4.3. Thanks for your help. Jim Durham To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
