Is there an autoneg > issue with the switch (some don't do autonegotiation correctly). There was a problem on older gigabit switches and for historical reasons was set up this way yet. Now they are on new ones and I asked them to put the switch port to autoneg. OK now for the speed part. I get 100/full after autoneg at boot. But when I start for example an scp session of big files (around some tenths of megabytes) from/to my pc, I get many link down messages..... The transfer begins at 9.7MB/s and then continuously decreases at about 7 and also 5 MB/s..... See below my /var/log/messages after reboot at about 09.30 this morning. For example at 10:23 and 11:05 I started scp sessions (single file of about 2.5Gb) Jan 26 09:34:54 tekkaman kernel: tg3: eth0: Link is down.
