I've been trying to understand numerous bug reports I've seen for hdparm over the past couple of months. I think they probably all boil down to the new libahci code not returning a correct result_tf in response to successful ATA_16/ATA_12 passthru commands. It seems to return a stale result_tf much of the time. perfectly reproduceable here on my Jmicron JMB360 PCIe SATA interface. I am totally lost when looking at libahci code though. Anyone got any ideas where the bug might be there??
