--BXVAT5kNtrzKuDFl Content-Type: text/plain; charset=utf-8 Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Hi, I am trying out 12.0-ALPHA6-amd64-20180914-r338675 vmdk with a VM with two CPUs. When doing "shutdown -h now" I get a lock order reversal, is this expected? According to https://www.freebsd.org/doc/faq/troubleshoot.html#idp59076936 = it is possible to get false positives from witness.
