Any relevant messages in logs?. Assuming we're talking about eth0

grep eth0 /var/log/messages

Some cards have issues when RX/TX offload is enabled. To check:
ethtool -k eth0

To disable offload (taken from help):

ethtool -K|--offload DEVNAME    Set protocol offload
                [ rx on|off ]
                [ tx on|off ]
                [ sg on|off ]
                [ tso on|off ]
                [ ufo on|off ]
               [ gso on|off ]
               [ lro on|off ]

If that doesn't work, the last thing to try is changing the kernel
module for the published by Via at
http://www.via.com.tw/en/support/drivers.jsp, I assume the needed file
would be http://www.viaarena.com/Driver/velocity_linux_v1.41.zip.

The easier way out would be to get a Intel or Broadcom NIC.
