Maybe your swap is not setup properly.  I think you need a swap 
partition that's 1.5 times your RAM.  For 1 G RAM, you need 1.5 G swap. 
  Check your swap in a terminal with:

paul :~$ cat /proc/swaps
Filename                                Type            Size    Used 
/dev/mapper/vgsda6-lvswap               partition       2047992 0       -1

In my case, suspend and hibernate work only the first time perfectly, 
then something fails to resume on the 2nd or 3rd time or it reboots. 
Gutsy's kernel still does not fully support hibernate / suspend.  You 
will find complaints on all distro mailing lists, so it's not an Ubuntu 
only problem.  Anyway, it's buggy after the first try.  IMHO, it's not 
worth reinstalling to get a larger swap, if that's what you need, 
because it still won't work well.

I also tried upgrading to Hardy and it's still broken there too.

If you have high speed connection, here's a talk by Matthew Garrett at describing the problem:
