Sam,
Has anyone seen this? While testing new systems I have observed that the 3rd on board ethernet stops working after days of moderate network load testing. I'm unable to ping out via the interface, or ping to the interface's ip address from outside. No errors are observed in logs, ifconfig, route, or ethtool. If I manually reconfigure the interface with ifconfig it works fine. (Leading me to think the driver or chipset gets in an odd state and needs to be reset.)
We are seeing this with R300 onboard NICs. Have not checked whether they are using the same chip, but somewhat likely.
The NICs are actually loosing the MAC address, system needs to be powered down to bring the NICs back to life.
Dell told us to shut down the OS properly as it happens even more often if you reset the server. Our R300s are used for RedHat cluster testing, so fencing operations are quite common tasks in that environment.
Updating the NIC's firmware (with lots of iSCSI-related fixes) has worsened the situation. The MAC address is even lost if the cluster is idle (no tests or services running, just node to node status communication going on).
