Again I really need to see the output from dmesg. Hi, Mark, It's really weird, isn't it?

Thanks again, Albert. ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
