On a Lenovo S10-3 running Fedora 14, I am no longer able to resume from suspend (or hibernate).
The problem began recently (about a month ago). Previously, suspend (or hibernate)/resume worked flawlessly. The netbook originally ran F12 and suspended resumed with no issues. After updating to F14, it still functioned properly. Then, suddenly, it ceased to function.
The suspend to ram appears to work (using either pm-suspend/hibernate or the equivalent gnome GUI controls), but when I attempt to resume from suspend to ram, the system simply boots normally: the system POST's and boots as if it was power cycled. I was previously able to hit a keyboard key and successfully resume; now I must hit the power button to initiate the reboot.
Hibernating is somewhat different. Sometimes it behaves like suspend to ram. It will appear to hibernate successfully, but require a power button press to recover (again, rebooting like a power cycle). Other times, it will hibernate then immediately (with no human interaction) resume (successfully!) from hibernate.
