6.1->6.2 gives ata controller reset failure

[Steve Franks]

Everything looks spiffy after my upgrade except all my sata disks are
gone.  Thank goodness the os in on a pata controller:

atapci1: <AcerLabs M5287 SATA150 controller> port
0xec00-0xec0f,0xe880-0xe887,0xe800-0xe80f,0xe480-0xe487,0xe400-0xe41f
mem 0xdffff800-0xdffffbff irq 21 at device 31.1 on pci0
atapci1: AHCI controller reset failure
device_attach: atapci1 attach returned 6

Thanks,
Steve
