The timing values used are different to those on the AMD 8111 even though the interface is similar. > It's stange that the driver is using CPI config. space by default > which not even documented in the datasheet.

This is a Geode. What makes you think there is even a PCI bus or that the 8111 interface isn't entirely a software construct. Geode PCI hardware is mostly smoke and mirrors ;) Alan -- 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
