Since it works with another operating system and a prior version of FreeBSD, I find it difficult to believe my hub is the problem. Could you tell me how I can determine my hub is at fault? My hub is old and has a 10base2 connector, which I'm using for other boxes. But my FreeBSD 4.2 box is using 10baseT/UTP. I have never experienced these types of stalls until I began using FreeBSD 4.2. Ken To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
