Take a look again of the mentioned calxeda... it looks like it only uses the compatible "calxeda,hb-ahci" handled by drivers/ata/sata_highbank.c and seems not using the ahci-platform.c obj-$(CONFIG_SATA_HIGHBANK) += sata_highbank.o libahci.o so imho the maximum 0x1 still should be right regards Frank > > Gesendet: Samstag, 05.
