How do I fix my Macbook's sleep issue (OHC2)?

I have a Macbook unibody (2.4GHz from 2010) with the OS 10.8.5. After updating to the latest operating system and software updates, my Mac will not stay asleep for more than 5 seconds whether or not it's running plugged in or not nor will it stay asleep by closing the lid or by menu command. I ran Terminal to determine that I'm having an OHC2 issue.

I do not use any USB or Bluetooth device (BT is shut off), I'm not sharing any devices over the network, I've turned off all the wake up options in my system preferences, I've reset my SMC, but I'm still having this issue. I've googled "wake=OHC2" and have come across a bunch of people with problems, but no known solution. Please help, I'm tired of shutting off the computer everytime.
