I just wonder why memcpy_count and bytes_transferred in /sys/class/dma/* is always zero. I guess the kernel version is relevant, but this a bit difficult to answer, since we have backported a huge chunk of raid, ioatdma and dca from 2.6.25 to 2.6.22... Do I miss something or do I need to enable something somewhere? Thanks, Bernd
