For the record, cherry-picking ff10e13cd06f3dbe90e9fffc3c2dd2057a116e4b (the periodic phy-crash-and-reset check) atop 2.6.36 seems to have fixed it: at least, the machine has been up for a day now without trouble. This commit doesn't seem to be in Greg's stable-queue yet, but seems like a good candidate. It's still rather gruesome that anything like this is even needed, but as long as it only fires every hour or so I guess I can live with it. Are there firmware updates or something that might fix this properly in the end? -- 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/
