--- Comment #3 from Mark Johnston <markj@FreeBSD.org> ---
(In reply to Konstantin Belousov from comment #1)
Indeed, this is the result of a corrupted callout structure:

(kgdb) p *cc->cc_callwheel[firstb & callwheelmask].lh_first->c_links.le.le_=
next
$12 =3D {
  c_links =3D {
    le =3D {
      le_next =3D 0x40,=20
      le_prev =3D 0xfffff800051ef9b0
    },=20
    sle =3D {
      sle_next =3D 0x40
    },=20
    tqe =3D {
      tqe_next =3D 0x40,=20
      tqe_prev =3D 0xfffff800051ef9b0
    }
  },=20
  c_time =3D 4,=20
  c_precision =3D 20,=20
  c_arg =3D 0x7fffffffef70,=20
  c_func =3D 0x15,=20
  c_lock =3D 0x18,=20
  c_flags =3D 22,=20
  c_iflags =3D 0,=20
  c_cpu =3D 0
}
