            Bug ID: 278422
           Summary: kernel panic related to IPv4 routes populated by bird2
                    when dxr routing algorithm used
           Product: Base System
           Version: 14.0-RELEASE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org
          Reporter: gshapiro@FreeBSD.org

While researching bug 278394, Marek recommended:

net.route.algo.inet.algo=dxr

Using that caused a kernel panic:
