When I start sleep (its hibernatemode 3), the screen goes dark, the hdd powers off and thats all. No moon appears, the normal poweron-lights are still there. Then I have to soft-poweroff the computer. Chameleon reconnizes sometimes a hibernation-image on reboot and says that the image is t old for booting.
I have OS X 10.5.7 with all updates installed. USB, Firrwire, BT, PC-Card, Sound, Display works fine.
I think its something with the kext, but which?
