unable to suspend with 3.4.0-4.9~precise1-generic 3.4.0

I was testing 12.04 with 12.10 kernel 3.4.0-4.9~precise1-generic 3.4.0.
When I suspend, systems wakes up automatically after few seconds and after unlocking the screen GUI is frozen, however it's still possible to log-in in tty1.

I was able to reproduce a bug also in 12.04 with 12.04 kernel.
