Hi list, Any body used titan GE device with more than 512MB physical memory? If buffer is getting allocated above physical address 0x1fff_ffff ( ie. 30 bit buffer address) we may have to consider setting XDMA_BUFFADDRPRE (0x5018 ) .This is not taken care in original driver. Any body had luck in enabling this prefix. I have tried enabling it and I could do flood ping with out packet loss. However when I do mass data transfer kernel getting panic. Further investigation showed kenel panics because DMA copies data to wrong address (which is being used). Any body had luck with this kindly share there experience? Thanks Anoop
