Hi Nathan, > Could you try the new ata_macio.c at > http://people.freebsd.org/~nwhitehorn/ata_macio.c? If that fails, also > try changing sc->max_mode to WDMA2. My hardware (ata-3) won't let me > test the UDMA modes, but at least the WDMA ones should now work in this > configuration. Had to drop it to WDMA2 and then the DMA i/o's completed. However, the GEOM use-after-free panic persists. I'll see if I can get some more info about that. later, Peter.
