Does the attached patch make any difference? diff --git a/drivers/ata/libata-core.c b/drivers/ata/libata-core.c index 4fbcce7..abebdcc 100644 --- a/drivers/ata/libata-core.c +++ b/drivers/ata/libata-core.c @@ -6712,6 +6712,7 @@ int sata_link_init_spd(struct ata_link *link) spd = (scontrol >> 4) & 0xf; if (spd) link->hw_sata_spd_limit &= (1 << spd) - 1; + link->hw_sata_spd_limit = 1; ata_force_spd_limit(link); Hm, this would force 1.5Gbps on all ports and devices, right? Cannot I just boot with "libata.force=4:1.5Gbps"? Thanks Guennadi --- Guennadi Liakhovetski
