cMP not waking up

Made a mistake: didn't remember not to try to activate old qmaster in 10.10.
I'm not sure if this is about it, but can anybody decypher this:

23.2.16 13:23:39,105 powerd[50]: com.apple.message.domain: com.apple.wake.failure
com.apple.message.signature: Drivers Failure
com.apple.message.signature2: NRP5(NVDA NVDA NVDA NVDA),P0P9(AppleAHCI ATY_Vervet ATY_Vervet ATY_Vervet AppleIntel8254XEthernet AppleIntel8254XEthernet)
com.apple.message.summarize: YES
SenderMachUUID: D88AA2E5-ABBC-3B2B-B53C-17A92A95F274

 

I just had a similar issue: My 10.10.5 did not wake up, i.e. neither Kbd nor Display worked (though the system log I checked after rebooting told me that the Mac kept running in the background, so it was not fully asleep as it should when I put it to sleep last night).

So the diagnostic info from Console.app showed this:

11.03.16 12:05:04,854 powerd[56]: com.apple.message.domain: com.apple.wake.failure
com.apple.message.signature: Drivers Failure
com.apple.message.signature2: NRP5(NVDA NVDA NVDA NVDA)
com.apple.message.summarize: YES
SenderMachUUID: D88AA2E5-ABBC-3B2B-B53C-17A92A95F274

Seeing the "NVDA" codes, I wonder if it's short for NVIDIA. I have a custom NVIDIA Graphics card installed (Geforce 660). Maybe the nvidia driver has some troubles on the Mac with this unregular card?
