This warning indicates that the driver failed to check dma mapping error on a buffer returned by dma_map_single() or dma_map_page() call. Looking at the the area where mapping is done, it appears it does call dma_mapping_error(). It does allocate several buffers in a loop, so it not obvious to me why the warning is showing up. I will follow-up on this to make sure it is not a false alarm, before I get the driver team involved. Thanks for reporting it. -- Shuah ------------------------------------------------------------------------------ Don't let slow site performance ruin your business.
