Googling around, I found similar complaints in the past for other nVidia controllers using the sata_nv driver (though I couldn't find anything about the MCP51). I tried compiling the version of sata_nv that comes with 2.6.26.5, but that did not solve my problems. I can provide further details if necessary.Does 2.6.27.5 make any difference? -- tejun
Yes, 2.6.27.5 works well. Thanks! --Elad -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
