Jeff, I changed line 53 of libata.h from "#undef ATA_DEBUG" to "#define ATA_DEBUG" and we got a bunch of compiler errors. Was that not what you wanted? Should I change ATA_VERBOSE_DEBUG instead?

We used a PCIe analyzer card to look at traffic as we booted Linux (build 2.6.19). We saw various PCI reads & writes as the system initialized PCI resources but we never saw what would amount to an 'Identify Device' command which I'm assuming the libata driver should do.
