That's weird. Link is up but EH is detected to be up but EH didn't probe it. Is the behavior reproducible?

Maybe FBS support doesn't work as advertised? Can you please try the following patch?diff --git a/drivers/ata/libahci.c b/drivers/ata/libahci.c index d38c40f..a2f4b68 100644 --- a/drivers/ata/libahci.c +++ b/drivers/ata/libahci.c@@ -444,6 +444,7 @@ void ahci_save_initial_config(struct device *dev, "controller can do FBS, turning on CAP_FBS\n"); cap |= HOST_CAP_FBS; } + cap &= ~HOST_CAP_FBS; if (force_port_map && port_map != force_port_map) { dev_printk(KERN_INFO, dev, "forcing port_map 0x%x -> 0x%x\n",
OK, will do thanks - I assume this'll force command based switching, with it's associated crappy performance tho'... I've ordered an 88SE9128 card (Hightpoint RocketRaid 620) as well, so I'll be able to compare the two, as well as a sata_mv 88SX7042 as well. Cheers, Tim.
