Umm... if you're hibernating to the same swap partition you're using
when the system's live... I'm pretty sure you can't do that... even if
everything does manage to fit, having sort out what belongs back in
ram and what doesn't ... it's not a very sane thing to expect the
kernel+userspace tools there to do. If I recall from last time I
considered setting it up on my system, software hibernate needs an
otherwise unused swap partition that's just a little bigger than the
amount of physical ram in your system.
