How frequently does this occur? it just started happening, which is wierd because the box has a month of uptime before upgrading the driver. Something may have gotten mucked up, but I'm trying to trace the actual cause to figure out what it might be. Its a T3 line, so its passing millions of packets in-between failures. I can toss te packets easy enough, but I've never seen this failure on a T1 line with months of uptime...so its baffling. thanks, Dennis To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
