It started sporadically and over time became more frequent. When I googled I found many references to heat problems. I then disabled rx/tx checksum offload and it seemed like it fixed it, but only for a short while. It got worse and ultimately died altogether. Had to disable and put a PCI NIC in. While it is normal to see the ifup/down a couple of times at boot, it is an abnormal indication when you begin seeing lots of them in /var/log/messages during normal operation. If you notice a "pause" for a short while in your network connection and then a tail /var/log/messages starts showing you these messages your NIC is probably dying. If you only see a couple of these at boot you're probably OK. -Mike
