Since the same libata-core.c works perfectly fine with sata-mv driver, but not ahci-mvebu, the problem might still be in the ahci-mvebu. The comment said: "sata_down_spd_limit should return if driver has not recorded sstatus speed". This probably means that ahci-mvebu does not record the expected "sstatus speed". I don't know what that is, but Damien probably does. >> @ Pali Rohar: >> I could't find the errata you mentioned.

I'm just an amateur. I did some bare-metal programming on MCUs, but the kernel is way too complicated for me.
