Every second person on the forums is also a moron.  I don't see the same
problems being reported here.

That would certainly do it.  Not because that's strictly a problem, but
because if you've changed the UUID you won't be mounting a swap at all!

First check "free", and make sure you really have enough swap space.
If you don't, run "sudo blkid" and find the UUID on the swap partition.
Check /etc/fstab, and make sure it's mounting the correct partition.
If you have a mounted swap, and the Swap/Free is less than the Mem/Used, you
don't have a big enough swap.  If it's even _close_ you might not have a
big enough swap.

If all of that looks good, check your /boot/grub/menu.lst - is there
a "resume=" option on the boot statement?  There shouldn't be...
