--- Comment #2 from commit-hook@freebsd.org ---
A commit references this bug:

Author: tijl
Date: Mon Oct 10 11:51:47 UTC 2016
New revision: 306960
URL: https://svnweb.freebsd.org/changeset/base/306960

Log:
  MFC: r306318

  Allocate a zeroed LDT.

  Failing to do this might result in the LDT appearing to run out of free
  descriptors because of random junk in the descriptor's 'sd_type' field.
