AFA logs are concerned, you need to look at /var/log/pm-suspend.log,
whether you are suspending or hibernating.

Read this page:

It shows you what to try, what to expect, and what to look at.  There is
more detail for suspend problems, but the rules are similar for hibernate.

The only other thing I can think of to ask is if you have many
non-standard kernel options in your /etc/grub.conf file.  I found that
nomodeset can be either a maker or breaker, depending on which kernel
you are running.  And more recently, VGA= was a killer for me too.
I have had suspend work for me successfully on FC6, F9, and now F14 (it
failed on F11 & F12 for me).  Hibernate worked for me only on F9 and
F11.  I haven't extensively tested it on F14 yet.
