Usually I find impossible to resume after hibernating my system.
The screen remains black and the system hangs.
I need to switch off and reboot.
Version-Release number of selected component (if applicable):
This problem seems not to follow a regular pattern.
I guess that it's more likely to happen if before hibernating, there are a number of processes opened and running (with a good amount of memory used/occupied).
Steps to Reproduce:
1.open some applications
2.System --> Shut Down --> Reboot
3.Try to resume from hibernate state
Impossible to resume.Need to switch off the system and boot again.
