Hmm... I don't see any timeout in the log you posted.  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.
