Created attachment 135536 [details] glxinfo Works fine until screen sleeps, after screen sleeps it will not wake up again. System is still alive as I can ssh in, but I cannot switch VT, and keyboard input seems to cause the GPU fan to spin faster. I also seem unable to kill Xorg via ssh, no matter what I try. MSI Vega 56, Artix Linux x86_64, linux-amd-staging-drm-next-git 4.14.0-rc3-26c860d55796
Please attach the corresponding dmesg output and Xorg log file.

I seem to have a similar problem. Laptop working fine under fedora 26; since ungraded to fedora 27 a few days ago; when the screen sleeps, it won't wake. For other reasons I am still using the fedora 26 kernel (4.12.x) - so the problem seems to be entirely due to changes in userland, or at least, outside the kernel, in libdrm or x driver. Am running gnome classic in x11 if that matters.

Please file your own report, then. The dmesg attached here looks clearly like a DC (or possibly ATOM BIOS) issue.
This should be fixed in Dave Airlie's drm-fixes-for-v4.15-rc2 branch.
I have a similar issue which is still present in 4.15-rc2. Though, in my case the system completly hangs after the screen wakes up from sleep and I can't even ssh in and there is nothing in the logs after a forced reboot. My GPU is a RX560.

In other words, an almost completely different issue. ;) Please file your own report.
Appears to be fixed, at least on the latest mesa-git
