Note that a fix to  bug that can cause a crash with vt was patched a few
days ago in HEAD and is scheduled to be MFC'ed to 10-STABLE in just a few
days. I have only seen reports of it triggering a crash on a resume from
suspend.

I have been running with the patch (three lines) since last Friday and have
exercised it quite a bit. Seems to fix the issue. The patch to
/sys/dev/vt/vt_core.c can be made by hand and the kernel rebuilt with
-DNO_CLEAN very easily.
