I know what the problem is. I just got a BIOS update tonight which was supposed to fix the issue. However, pata_amd.c still failed spectacularly at configuring the device whereas pata_cs5536 worked fine. For kicks I switched my driver over to using PCI config registers instead of MSRs. And it still worked! When I changed my driver I did a quickie conversion from wrmsr() to pci_write_config_dword(). If I use pci_write_config_byte() instead (like pata_amd.c), things fail miserably. A register dump reveals that any value I write becomes a 0. Yay! -- Martin K.
