            Bug ID: 212918
           Summary: [11.0-RC3] System hangs after suspend/resume if
                    virtualbox VMs are running
           Product: Base System
           Version: 11.0-STABLE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern
          Assignee: freebsd-bugs@FreeBSD.org
          Reporter: afiskon@devzen.ru
                CC: freebsd-amd64@FreeBSD.org
                CC: freebsd-amd64@FreeBSD.org

Steps to reproduce:

1. Launch some virtualbox VMs
2. sudo acpiconf -s 3
3. Resume

Expected behavior:

System continue to run.

Actual behavior:

Black screen, system doesn't respond to any hotkeys. Impossible to reboot a
system by typing commands blindly or create a kernel dump using Ctr+Alt+F1,
Ctr+Alt+Escape.

Hardware: Fujitsu Lifebook E733

uname -a:
```
FreeBSD e733 11.0-RC3 FreeBSD 11.0-RC3 #0 r305786: Wed Sep 14 02:19:25 UTC =
2016
    root@releng2.nyi.freebsd.org:/usr/obj/usr/src/sys/GENERIC  amd64
```

Naturally it could be a bug in virtualbox driver or port, not FreeBSD kernel
itself.
