Since updating to FreeBSD 12.0, I have been seeing this message when I
boot-up.

sendmsg on em0: No buffer space available

It is the third line in the following message displayed while booting up.

Feeding entropy: .

It was not present in older versions of FreeBSD. I don't know what it
means or if it is important.
