I tried to disable some options of the card with : ifconfig re0 -rxcsum -txcsum -tso -lro -vlanhwtag but nothing as changed. I just tried to download a big file (FreeBSD 7.1-REL DVD iso in fact) to see if the deconnection occurs even during a transfer. The DVD downloaded successfully and I verified that the MD5 are OK. BUT, /var/log/messages continue to tell me that: Feb 4 16:09:29 term003 kernel: re0: link state changed to UP Feb 4 16:19:26 term003 kernel: re0: link state changed to DOWN Feb 4 16:19:30 term003 kernel: re0: link state changed to UP Feb 4 16:19:32 term003 kernel: re0: link state changed to DOWN during the transfer (which worked OK). I don't know if that can help someone to help me ;) Thanks, Martin _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org" I have a solution to this well a work around. Add -tso to the relevant line in /etc/rc.conf ifconfig_re0="inet 192.168.1.103 netmask 255.255.255.0 -tso" Adding -tso stops the link up / link down problem. Now I am understand that this may increase cpu if the traffic on the nic is high. I am sure some one the list will know of any other implications this may have. It is a known problem and I site I read the bug had been submitted so hopefully it wont exist in 8.0 Regards Graeme _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
