I've had a search for threads relating to this - and find that the information is scattered through a dozen or so with unhelpful titles etc. So here is the dope:
On clean installs of FC4 (also had this with FC2 and seen it reported with FC3, just not as frequently) we find that there is sometimes trouble mounting the swap partition. Even if the swap partition
is mounted, on examining /etc/fstab we find a load of absolute Francis Ford (which is to say: Crappola) as the swap partition label.
This is an issue known to
Bugzilla.

What's happening here is that for some reason, mkswap does not appear to be
clearing out the section of the swap partition header that holds the label.
Then later we see that there's still something in the label section and decide
we don't need to assign it a new label. Unfortunately, there's only garbage in
the label section.

I got this problem too from a fresh install. But swap is mounted. You can check
that with 'top' command or simply use system monitor. if not or you want a new
label for swap, you could do this:
Code:
su
/sbin/swapoff /dev/hd? !only needed if your swap is on
/sbin/mkswap -L swap /dev/hd?
/sbin/swapon /dev/hd?
this will give you an output like:
LABEL=swap, UUID=e074f449-5f5e-4b97-a2ae-07e82ef96664
then you can go back to fstab to get rid of the garbage:
LABEL=swap swap swap defaults 0 0
or you can use the UUID

Chances are there is no problem for you. With a great deal of RAM, there is a valid argument for not using a swap partition at all! (It would speed up your system for a start.)
But if you seem to have intermittent hanging issues associated with mounting the swap partition then this is probably the cause.
The above also explains why there is a LABEL= entry in there at all ... though .dev/hdx works just as well.
