I remember re(4) in 6.x also have a couple of bus_dma(9) bugs. How about applying the following revision? http://svnweb.freebsd.org/base?view=revision&revision=175337 Not sure whether it shall apply cleanly. Alternatively try replacing BUS_DMA_ALLOCNOW to 0 in bus_dma_tag_create(9). > Eugene Grosbein _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
