Description of problem:
When attempting to suspend the computer, it spins the hdd down, and goes to the blue bootsplash screen from plymoth, then hangs and never recovers. I have to power the computer down, and boot fresh. This happens whether from pm-suspend or from the KDE suspend option. I also had the same issue in the GNOME variant Fedora and several Ubuntu distros.
