My .02: I think it's crucial at this juncture for people to not only say "it worked with those options" or "it didn't work with those options", but also make sure they indicate whether the boot messages (dmesg) show that indeed DMA was turned on when the options where added. 1) "dmesg >dmesg.old" 2) create/edit /boot/loader.conf.local 3) reboot 4) "dmesg >dmesg.new" 5) diff dmesg.old dmesg.new For various reasons a particular hardware setup may not activate DMA mode even after adding the loader options because of things like BIOS settings, cabling issues or hardware bugs. -- Philip J.
