Dear Devs,
ive got this really annoying issue with multiple boards:
- ASRock FM2A75 Pro4
- ASRock A88M-HD+
- ASUS A78M-E
The simptome is the same in every board, but just with A8-7800K Trinity(ARUBA). I've also tested with A10-7700K Kaveri(GCN1.1), but there was no problems at all. So I put the PC to S3 sleep, than wake it up. The monitor which uses DVI connector, works perfectly, but the HDMI one is mostly black,stays at sleep, doesnt displays information(out of range, etc), but sometimes a really flickering screen comes in for a few momements than disappears.
I hope its still a non-listed bug, I've checked multiple reports, but doesnt find thisone. Look at the attachments, dmesg log added.
Thanks
