I currently have a Nexus 3048TP which presents some concerning messages about the NVRam when it's booting. I've attached a full boot log with important parts highlighted/bolded.

I had read that these messages may mean that the NVRam is faulty and that it should be replaced/RMA'd. I've already tried running "write erase", but these errors still appear after a reload.
Apart from these messages, everything appears to be working normally (config and OS images persists through reboots, no errors while running nxos, etc.)
Is this something I should be concerned about? Are there any additional tests I can perform to determine whether this is a hardware issue?
