            Bug ID: 270460
           Summary: i386 guest panic when booting VirtualBox client
           Product: Base System
           Version: CURRENT
          Hardware: i386
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org
          Reporter: pjfloyd@wanadoo.fr

I have no problem booting other i386 versions in a VBox VM.
Host is amd64 running FreeBSD 13.1.

I don't remember when this first started, something like 6 months ago.

Because of this problem I am unable to do any testing of Valgrind on 14.0 i=
386.=20

Here is the start of the panics from the VBox VM serial output.
