Thanks for the suggestion.

It looks like the problem is related to virtualbox-ose-kmod installed
from the FreeBSD package repository not being compatible with 11.1.

I'm running virtualbox-ose-5.1.26 and virtualbox-ose-kmod-5.1.26 on
11.1-RELEASE. Rebuilding virtualbox-ose-kmod from ports and keeping
virtualbox-ose from packages fixed the problem.
