Weird, because every now and again my Macbook will just die after waking up. I also find that while initially it was really fast and worked great, it's now really slow and takes up to 10 seconds, while my linux laptop (which doesn't even have an SSD) wakes up pretty much instantly
Is there anything suspicious in the system log? I'm guessing that you might have a kext (like for VMWare Fusion of VirtualBox) that's misbehaving when waking up.
