For the sleep/wake issue, I got boot up with no screen when wake from sleep, and it reboots again.
I've also tried darkwake=0,10,8,no, but no luck.
So I checked
Code:
pmset -g log | grep -i failure
in Terminal, and I found different outputs using keyboard or power button to wake up.
Power button:
Code:
Drivers Failure during wake due to GFX0(),SAT0(),GLAN(IntelMausi):
Keyboard:
Code:
Darkwake Exit Failure during wake due to 0x34053000000032:
I'm curious what did you have in your terminal using the command, since I think it could be bluetooth and ethernet problem.
