l guess I will add my issues to this list! Specs are:
Asus P7H55-M Pro motherboard
intel core i5-760 CPU
8 GB G.Skill Memory
Powercolor Radeon HD 7950
OS X Yosemite and El Capitan
With this system as well as my main rig, which has a Gigabyte Z97 mobo and core i7-4790k in it, I can not properly wake from sleep.
When the dsdt from this site is in place for my Asus motherboard, (using clover 3320) I can't even boot at all. So I have to go dsdt free. (My BIOS is 1604)
The difference I have between the two OS versions is that with El Capitan, I can use the keyboard or mouse to invoke a wake up but in Yosemite, I have to use the power button. In both cases, the video never comes up. I've confirmed that with my setup(s) the system is actually frozen. I did this by installing Teamviewer. When I try to wake up the computer, I am not able to remote into it. Perhaps more issues than just the video not coming back up again.
