Hi.

  Thanks for your response!

It is somewhat hard because it goes from 'hangs almost always' on ubuntu's
4.4.0 kernel to 'hangs every time' on 4.7.3.

Also I assume xorg and its version may play some role in that because it
doesn't happen in text console.

It also looks like that there is some sort of dependency on how log it was off
- 4.4.0 almost never wakes up overnight.

I'll try to play with different versions to see if I can find a pattern...

I was hoping that there is some way to delay radeon awakening for after I get
net and can tail debug logs - so if there are errors it would dump them.
