I'm having an issue that sounds similar to one from back in January, but under Linux rather than Windows. I upgraded to amdgpu v18.20.2.15, and started seeing that sometimes the display wouldn't come back from a wake from display-off. The machine keeps running, and I'm able to ssh into it (see dmesg snippet below) but it seems to need a reboot for the display to come back.

I rolled back to 17.50-511655, and that seems fine for now.

• OS: Ubuntu 16.04.4 LTS
• Kernel: 4.15.0-24-generic #26~16.04.1-Ubuntu SMP x86_64
• CPU: Intel(R) Core(TM) i5-3450 CPU @ 3.10GHz
• Motherboard: MSI MS-7758/Z77A-G43 (MS-7758), BIOS V2.13 03/07/2014
• Graphics card: MSI RX 580 Armor 8GB (AMD POLARIS10)
• Displays: LG 27UD68P, Acer S277HK (both connected via DisplayPort)

Here's what dmesg said:
