P55M-UD2 Sleep issues

[Cougarcat]

I was hoping Yosemite would magically resolve this, but alas.

I have this bizarre sleep issue where the computer will go to sleep fine, but it will randomly wake up again, although the display doesn't come on. Sometimes it will go back to sleep again on its own, but it will inevitably wake up again.

I'm not sure how to troubleshoot this. Below is my peset -g after it woke up, but I don't see anything obvious. Any ideas? Thanks.

Edit: sorry, meant to put this in general, could a mod move it? Thanks.
