There are some known-buggy chipsets also. One still around is the Nvidia CK804/MCP55, under certain patterns of spatially-local pending reads and writes to the memory controller, a 64-byte request would occasionally be returned with the wrong offset. I was hitting it with some 27-Gbit adapters and managed to capture it on a PCI-e protocol analyser. Rsync between network and local disk would hit sometimes too. -- Daniel J Blueman -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
