On 2.6.24-rc1 (AMD Opteron 1216), my sata_nv driver produces this
output on bootup:

ata2: EH in SWNCQ mode,QC:qc_active 0x1 sactive 0x1
ata2: SWNCQ:qc_active 0x1 defer_bits 0x0 last_issue_tag 0x0
ata2: ATA_REG 0x40 ERR_REG 0x0
ata2: tag : dhfis dmafis sdbfis sacitve
ata2: tag 0x0: 0 1 0 0
ata2.00: exception Emask 0x0 SAct 0x1 SErr 0x0 action 0x6 frozen
...
ata2.00: status: { DRDY }
