In my setup with a MV88SX5041, this new driver doesn't recognize any 
disk connected to the controller. The controller seems to be 
recognized fine, but nothing else:

sata_mv version 0.22
ACPI: PCI interrupt 0000:02:08.0[A] -> GSI 26 (level, low) -> IRQ 209
MSI INIT SUCCESS
sata_mv(0000:02:08.0) 32 slots 4 ports SCSI mode IRQ via MSI
ata3: SATA max PIO4 cmd 0x0 ctl 0xF8A22120 bmdma 0x0 irq 209
ata4: SATA max PIO4 cmd 0x0 ctl 0xF8A24120 bmdma 0x0 irq 209
ata5: SATA max PIO4 cmd 0x0 ctl 0xF8A26120 bmdma 0x0 irq 209
ata6: SATA max PIO4 cmd 0x0 ctl 0xF8A28120 bmdma 0x0 irq 209
ata3: no device found (phy stat 00000000)
scsi2 : sata_mv
ata4: no device found (phy stat 00000000)
scsi3 : sata_mv
ata5: no device found (phy stat 00000000)
scsi4 : sata_mv
ata6: no device found (phy stat 00000000)
scsi5 : sata_mv

(starting at scsi2 'cause the first 2 are on a ata_piix SATA).
/proc/interrupts shows no interrupts received:

209:          0          0   IO-APIC-level  libata

Thanks!
