Ye Olde Random Reboots?

[firecall]

So my Alienware Alpha R1 has been rock solid in use.

But it's randomly rebooting in the night, and this morning when I tried remote into it. (It's on Ethernet, so maybe receiving wake on lan signals). Not kernal panics, just random reboots.

Going by the console I can see some Darkware Exit Failure messages etc.. around the same times as it's restarting.

Is this a thing? I'm guessing power management or sleep might be a known Hackintosh issues? (of course it could be bad ram)

See Log example below.

Thanks in advance!
