What happens if a filesystem is frozen and I hibernate?
Will it be thawed when I resume?

If you froze it yourself, then you'll have to thaw it yourself.

So hibernate will not attempt to re-freeze a frozen fs and, during resume, it 
will only thaw filesystems that were frozen by the suspend?

Right now it doesn't freeze (or thaw) any filesystems.  It just sync()s them
before creating the hibernation image.

Thanks. Yes I realise that :)
I wasn't clear, I should have said:
So hibernate should not attempt to re-freeze a frozen fs and, during resume, it
should only thaw filesystems that were frozen by the suspend.

However, the fact that you've seen corruption with the XFS filesystems frozen
before the hibernation indicates that the problem occurs on a lower level.

And that was why I chimed in - I don't think freezing fixes the problem (though 
it may make sense for other reasons).
