macbook professional – What would trigger the next error: ‘Eject “Apple SSD – Knowledge” earlier than disconnecting or turning it off’

I simply noticed the message beneath on my 2015 MacBook Professional operating macOS 12.2.1. It appears bizarre for macOS to be complaining about ejecting an inner SSD that I might by no means really eject.

What might trigger this? Is there something that I have to do to repair it or diagnose it?

I’ve no exterior drives hardwired to this laptop computer, if it issues.

I noticed this after unlocking my Mac. Proper earlier than that, I woke it up by typing on my exterior keyboard. This laptop computer is normally docked and related to KVM by an IOGEAR GCS62DP KVM swap.

Here is output from diskutil record:
