I've tried the new version of the driver on our Supermicro 6024H-T
server with the Marvell 88SX6081 8-port SATA controller. There are
six disks in the server, if that makes any difference.
When booting up, the driver issued the following text:
sata_mv version 0.22
ACPI: PCI Interrupt 0000:02:03.0[A] -> GSI 56 (level, low) -> IRQ 20
sata_mv(0000:02:03.0) 32 slots 8 ports unknown mode IRQ via INTx
ata1: SATA max UDMA/133 cmd 0x0 ctl 0xF8922120 bmdma 0x0 irq 20

ATA: abnormal status 0x80 on port 0xF892211C
ATA: abnormal status 0x80 on port 0xF892211C
At that point the machine freezes hard -- the SysRq key doesn't work.
lspci -vxx output for the controller:
