I have this same issue with a compaq C700 series (C714nr) and all versions of ubuntu including Karmic. I can suspend once and it works fine. Second time, it won't wake up. I just updated the BIOS from F.06 to the latest F.34 thinking it would help but I still have the same issue. I'm a nooby though. I've been using ubuntu since 7.10 but don't know much about what happens in the background. If there is anything I can do to help solve it, let me know.
