On an ASRock 939Dual-SATA2 board, the sata_uli driver recognizes the onboard 
SATA controller (PCI ID 10b9:5289 rev 10, Subsystem 1849:5289), but fails to 
see an attached harddisk (the BIOS identifies the harddisk correctly, so a 
hardware failure is unlikely). sata_uli apparently sees _something_ is 
attached, but doesn't get further. dmesg says:

libata version 1.20 loaded.
sata_uli 0000:00:12.1: version 0.5
GSI 18 sharing vector 0xD1 and IRQ 18
ACPI: PCI Interrupt 0000:00:12.1[A] -> GSI 19 (level, low) -> IRQ 209
ata1: SATA max UDMA/133 cmd 0xEC00 ctl 0xE082 bmdma 0xD880 irq 209
ata2: SATA max UDMA/133 cmd 0xE000 ctl 0xDC02 bmdma 0xD888 irq 209
ata1: SATA link up 1.5 Gbps (SStatus 113)
scsi0 : sata_uli
ata2: SATA link down (SStatus 0)
scsi1 : sata_uli

No disks are found, even though the link (on ata1) is detected.

Verified both with an x86 and an x86_64 kernel, and both 2.6.15-rc5 and 
2.6.15-rc5-mm2.

Any ideas?
