Via Velocity VT6122 Unstable in Linux
After much experimenting in Debian Etch and Slackware 11, with various 2.6.x kernels up to and including 2.6.22, the VT6122 gigabit ethernet chipset, combined with either the built in via_velocity driver or the via supplied velocityget driver, results in an unstable link under load.
When the network is under heavy use (copying a file over samba/netatalk counts), the following appears multiple times in syslog indicating the continual reset of the network.
Aug 27 14:31:13 Enterprise kernel: eth0: failed to detect cable link
Aug 27 14:31:16 Enterprise kernel: eth0: Link auto-negotiation speed 1000M bps full duplex
Based on this, I do not recomend the use of Velocity based cards in Linux computers.
