Ah, okay, the interesting part is in the full log, the ACPI GTF sequence itself is finishing fine but the next NCQ READ command is timing out. The BIOS is enabling non-zero buffer offsets and DMA setup FIS auto-activate. It's likely that the controller isn't being configured correctly leading to mismatch between the behavior expected by the controller and the actual drive behavior. Hmm.... I'll look further into it tomorrow. For the record, can you please attach the full log, lspci -nn output and dmidecode output here? Thanks. -- tejun
