Dear Devs!
I've got this really annoying issue with multiple boards:
- ASRock FM2A75 Pro4
- ASRock A88M-HD+
- ASUS A78M-E
- ASUS F2A85-V EVO
The simptome is the same in every board, tried with A8-5500, A8-5600K Trinity and A10-6700 Richland(Aruba). I've also tested A10-7700K Kaveri(GCN1.1) with FM2+ boards, but there was no problem at all. The same behavior if i connect the hdmi cable after boot.
Seems like the bug is only exist when i manually take the computer to S3. After delayed sleep, it wakes perfectly.

Additional info:
Multiple kernel and xorg versions even with:
- Ubuntu,
- PartedMagic.


Steps to reproduce:
So just the PC to S3 sleep, than wake it up. The monitor which uses DVI connector, works perfectly, but the one at HDMI or DP is mostly black, stays at sleep, doesnt shows any information(out of range, etc), but sometimes a really flickering screen comes in for a few momements than disappears.
Logs attached.
This task depends upon
