Modified Files: src/sys/dev/pci: pciide_common.c Log Message: pciide_dma_dmamap_setup(): If we end up with a DMA segment with an odd length, unload the map and return EIO. Some controllers get really upset if a DMA segment has an odd length. This can happen if a physio user performs a virtually-contiguous I/O that starts at an odd address and spans a page boundary where the resulting physical pages are discontiguous. Ultimately, it's up to the physio user to paint inside the lines, but this will prevent the disk controller from wandering off into the weeds, at least.
