    This WARN should likely be looked at by someone, but it doesn't seem to
    be the main culprit.

    This is why the hard disk failed to resume, somehow the drive shows a
    capacity of 149GB after resume but only 128GB before. What's the actual
    capacity of the drive? I suspect the drive has a host protected area on
    it, and somehow the HPA isn't showing up after we resume.

    Can you post the dmesg log from normal bootup?
