Comment 4 for bug 576135

As reported by another poster in bug #550479 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/550479/comments/9

A simple work around for this issue is to remove the SD or other media card from the internal card reader on the front of the laptop. I had forgotten I had an SD card in there (it's never been an issue before) but sure enough I removed it and was able to suspend/resume perfectly.
