Ok, I got the suspend / resume process logged quite complete now, it
took me some time though to save the data due to the inaccessibility of
the root filesystem after resume. But (a modified version of) netcat
finally was my friend :-).
So below you'll find all messages from "kern.*" between the point when
calling "s2ram -f -p" up to the point when the system is back. The
requested libata messages are included. Please let me know if any
additional data would help.

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?
