Somehow I managed to get a backtrace (it seems to be correct):

  Crash version 9.99.82, image version 9.99.93.
  WARNING: versions differ, you may not be able to examine this image.
  crash: _kvm_kvatop(0)

the last change I could find which might be relevant was in sys/kern/sys_generic.c 1.133, but that
was before 9.99.93, so I am not sure where to look.
