hmm...
Maybe, you are doing panic because of kmem in fwohci_task_sid.

  static void
  fwohci_task_sid(struct fwohci_softc *sc)
  {
     :
        buf = kmem_alloc(OHCI_SIDSIZE, KM_NOSLEEP);
     :
        kmem_free(buf, OHCI_SIDSIZE);
  }


I think that I can evade by replacing these to malloc/free or allocate
a static buffer like newrom_space.  However, my machine can't reboot
now.
Could you wait until the weekend?
