HP has issued a critical customer advisory regarding some of their high performance server adapters. I’ve had a number of customers impacted by the NC522 and NC523 10Gb/s server adapters losing connectivity. It’s good to see there is a firmware update now that may solve this.
Customer Advisory c02964542, ProLiant and StorageWorks Systems: Certain NC-Series and CN1000Q Network Adapters – FIRMWARE UPGRADE REQUIRED to Avoid the Loss and Automatic Recovery of Ethernet Connectivity or Adapter Unresponsiveness Requiring a Server Reboot to Recover, has been released/revised.
[Updated 22/03/2021] This article is now quite dated and HPE should have long fixed this firmware issue in their NIC’s. This should be viewed as historic only.

IMPORTANT: The network adapter firmware and driver upgrades provided in the Resolution are required to prevent the loss and recovery of Ethernet connectivity, or adapter unresponsiveness requiring a reboot to recover, from occurring. HP recommends performing these upgrades at the customer’s earliest possible convenience. Neglecting to perform the recommended action and not performing the recommended resolution could result in the potential for subsequent errors to occur.
The network adapters listed in the Scope section (below) may encounter either of the following:
* The adapter may temporarily lose Ethernet connectivity, and then automatically recover.
* The adapter may stop responding, requiring a server reboot to recover the operation of the adapter.
Note: There is a low probability of this occurring when operating under a normal network workload.
