After opening the lid the screen is either black (no backlight) or the lock screen is shown but the system is freezed. There is no further reaction from the system (I can't switch via Ctrl+Alt+F1..9. Just MagicKey+RB would reboot the system. I have appended my syslog from the suspend to the freeze.
