We bounce when we think an address is greater than the number of bits a device can DMA directly to. So either the max_pfn or the dma_mask is being set wrong. > Well the c110 is the only model I use with NCR 53C720 & LASI ASIC interface > (i.e. NCR 53C710) Either of these drivers may not be setting the corresponding dma_mask. I need to check. grant _______________________________________________ parisc-linux mailing list parisc-linux@lists.parisc-linux.org http://lists.parisc-linux.org/mailman/listinfo/parisc-linux
