Created attachment 275681 [details] dmesg output I've been testing the new 4.17 kernel, which finally works for me with the new AMDGPU DC and DP MST monitors (4.15 and 4.16 did not). However, after the system is idle for long enough for DPMS to activate, the monitors will turn off, but never turn back on. Despite the monitors not working, I was able to SSH into the machine and obtain the output of dmesg, which is attached. I am using a Tonga GPU (Sapphire R9 380). I would be happy to test any patches that are available or provide any other necessary information.
