Hello!
I'm trying to implement the hibernation mode on IMX6Q and Android, but I have some problems with resuming process. Sometimes the system works fine after resuming from hibernation, but more often there are errors like:

What can cause these errors?
Any ideas are welcome, thank you in advance )
