It took a few days to discover that my problem was a hardware IDE problem, and not a network problem. Bit errors appeared when I copied remote files onto the local disk and then ran md5sum on them. When the files were large enough, bit errors silently introduced by the IDE interface resulted in MD5 mismatches. The answer on this board case was to disable IDE DMA. -- Jamie
