There are some fixes for bad hibernation performance in Linux 3.2.24.
You can try these out by applying
<http://git.kernel.org/?p=linux/kernel/git/bwh/linux-3.2.y.git;a=patch;h=6ed6791a1697afcb1615b4252d0c304a743b5f4d>
following the instructions at
<http://kernel-handbook.alioth.debian.org/ch-common-tasks.html#s4.2.2>.
