Another SATA device with spurious NCQ completions

From:

The following error consistently appears at apparently random intervals in syslog:

kernel: ata1.00: exception Emask 0x2 SAct 0x1001 SErr 0x0 action 0x2 frozen
kernel: ata1.00: (spurious completions during NCQ issue=0x0 SAct=0x1001

Controller is ATI SB600 using the AHCI driver.
64-bit DMA is disabled.
Disk is:
ata1.00: ATA-7: ST3160812AS, 3.ADJ, max UDMA/133


Can't we just turn off NCQ automatically when this happens?
