While rebooting cp3034 for kernel upgrades today, the host failed coming up with the following message:
Enumerating Boot options... Done UEFI0107: One or more memory errors have occurred on memory slot: B3. Remove input power to the system, reseat the DIMM module and restart the system. If the issues persist, then replace the faulty memory module identified in the message. UEFI0058: Uncorrectable Memory Error has occurred because a Dual Inline Memory Module (DIMM) is not functioning. Check the System Event Log (SEL) to identify the non-functioning DIMM, and then replace it. UEFI0030: A keyboard device is not connected to the system. Connect a keyboard device to the system. Press F1 to continue, F2 for system setup, F10 for lifecycle controller, F11 for boot manager.
The system did boot properly after a powercycle. There are a few "uncorrectable memory errors" in SEL though:
