I recently built a new machine with a Gigabyte GA-MA790X-DS4 motherboard and an AMD 9750 Phenom quad CPU. The Ethernet interface is a RealTek "RTL8169S/8110S/8211B media interface" as described by dmesg. I installed FreeBSD 7.0/amd64. I have been having a number of network problems with this system. I first noticed that Firefox was getting "incorrect Message Authentication Code" messages. I thought this might be a Firefox problem, but I noticed on a couple of other web sites that filling in message-posting pages occasion- ally failed with "not all requested fields filled in" for no reason (a simple retry wucceeded). The kicker came when I tried to use scp(1) to copy some files over the Internet to a remote machine: % scp *.JPG foo@remote.host:images Password: MVC00001.JPG 22% 152KB 152.0KB/s 00:03 ETAReceived disconnect from nnn.nnn.nnn.nnn: 2: Corrupted MAC on input. lost connection % scp *.JPG foo@remote.host:images Password: MVC00001.JPG 0% 0 0.0KB/s --:-- ETARead from remote host remote.host: Connection reset by peer lost connection % scp *.JPG foo@remote.host:images Password: MVC00001.JPG 0% 0 0.0KB/s --:-- ETAReceived disconnect from nnn.nnn.nnn.nnn: 2: Bad packet length 3694804283. lost connection I have seen other "Bad packet length" messages with different lengths given. I suspect a bug in the RealTek's driver, but I don't know for sure. Any suggestions? Where's the proper place to report this, and what further information could I provide in order to help track this down? Thanks. Terry R. Friedrichsen bsd@bunker-ranch.com
