Hi, sorry if this is in the wrong forum. I have a 2014 Macbook Pro with OS X El Capitan GM. Upon waking the Macbook, it crashes (I get the black screen) and it restarts. I saved the dialogue it gives me. Please let me know if it gives a reason for why it crashes. Thanks.

This worked for a bit but has happened a few more times. May have to do a fresh install of 10.11.
 
I am having the exact same problem with my MacBook Air (13 inch, Mid 2013). I just did a clean install of 10.11 and it still crashes often upon waking. If you find a solution, please post it! Thanks!

Here's my log:
