Do you have anything in your /var/log/pm-suspend.log?

What exactly are the hibernate messages in the messages log? Anything in

I seem to recall that you had the exact same problem last year with your

$ sudo lshw > lshwtbdesktop.txt

to pastebin?

One other thing you might consider trying is installing mcelog and
seeing if you can trap anything with that:
