Could you boot having the following line in /boot/loader.conf: hw.usb2.uhci.debug=15 And send new dmesg. Patch you can try in the meanwhile: Edit /sys/dev/usb/controller/usb_controller.c: - usb2_dma_tag_setup(bus->dma_parent_tag, bus->dma_tags, - dmat, &bus->bus_mtx, NULL, 32, USB_BUS_DMA_TAG_MAX); + usb2_dma_tag_setup(bus->dma_parent_tag, bus->dma_tags, + dmat, &bus->bus_mtx, NULL, 30, USB_BUS_DMA_TAG_MAX); This will reduce the DMA bits to 30. --HPS
