I think it is phk's changes. puc allocates a struct resource, but not
the private part, so the rman_set_* won't work:
rle->res = malloc(sizeof(struct resource), M_DEVBUF,
M_WAITOK | M_ZERO);
if (rle->res == NULL) {
free(pdev, M_DEVBUF);
return (ENOMEM);
}
rman_set_start(rle->res, rman_get_start(res) +
sc->sc_desc.ports[i].offset);
rman_set_end(rle->res, rman_get_start(rle->res) +
ressz - 1);
