Hi Gerald, I can confirm exactly the same behaviour on my EEEPC 1005HGO. After some update, hibernation did not work any more - exactly as you described. Someone pointed me to the kernel maintainers, but personally I think it is more a problem with pm-utils. I changed from grub-legacy to grub-pc at the same time, but reverting to grub-legacy let the problem not disappear. So it might be pm-utils, as the kernel was not changed on my system. Suspend-to-ram works perfectly, and, just as you described, when I am running duspend-to-disk and want to restore it, it is starting, then suddenly reboots/resests. You seem more experienced than me, maybe you might want to file a bugreport?
