I have a client with two servers with BCM5721 dual-NICs which, when tested, show one NIC as passing with flying colors, while the other has this NVRAM error. Not sure why, but it’s rather annoying. Broadcom told me I might want to have that looked at by my hardware vendor.
The servers are fine though…no weird errors as a result. It’s just the b57udiag program saying that the NVRAM has issues.
Anyway, here is what I see when I run the diagnostics, tell me if you have something like it:
