after extensive testing I've found that the latest V7.1 and the included default 1.6 kernel still has random freezing issue.
The phone doesn't respond at all and you have to do the volume down + home + power button combo to do a hard reboot.
Flashing morokernel v4.6 or any morokernel for that matter eliminates this issue.
P.S. the battery life is definitely better on stock edge kernel. It's the random freeze/reboot issue that bugs me.
@fivanbe would it be helpful if i provide logcat for your reference.
Please let me know and thank you for this next to perfect rom for our s7e.
Peace.
