It is not valid to pass BUS_SPACE_UNRESTRICTED to bus_dma_tag_create()'s nsegments parameter as it is interpreted as a very large segment count. Subsequent allocation operations on the tag will preallocate some multiple of that count. BUS_SPACE_UNRESTRICTED therefore indicates something like: malloc(infinity).
