For searchability, here's a few of the lines I think are most useful. Again, the full dmesg section is attached to the original report.

Created attachment 141955 [details] kernel warning + stack trace - from when HDMI monitor is turned off and back on Up to date Arch Linux, including: linux 4.18.12.arch1-1, xf86-video-amdgpu 18.1.0-1, mesa 18.2.2-1, opencl-mesa 18.2.2-1, xorg-server 1.20.1-1, and plasma-desktop 5.13.5-1. (Recently installed system that STARTED with: linux 4.18.9.arch1-1, mesa 18.2.1-1, and opencl-mesa 18.2.1-1.) It was also doing this then. $ lspci -k | grep VGA 03:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Ellesmere [Radeon RX 470/480/570/570X/580/580X] (rev e7) Subsystem: XFX Pine Group Inc. Ellesmere [Radeon RX 470/480/570/570X/580/580X] Kernel driver in use: amdgpu Kernel modules: amdgpu It's the: XFX AMD Radeon RX 580 GTS Black Edition 8GB GDDR5 PCI Express 3.0 I have (5) Acer K272HUL bmiidp monitors hooked up via DisplayPort. Left 2 are chained, and right 2 are chained. ASRock EP2C602 Motherboard w/ P1.90 BIOS. (2) Intel Xeon E5-2690 (v1). Anytime a monitor turns off, it causes a couple of kernel warnings and stack traces. Usually 2-3 warnings each time. When the monitor turns back on, it just logs what are I think are (3) expected "[drm]" lines about the "new" connection. See attached file for a sample of the kernel warnings/stack traces. The first part is when a monitor turned off, and the last part is when it turned back on. By turned off/on, I mean regardless of if I press its power button on the monitor, pull the plug and plug it back in, or if a graphics issue somewhere in a driver or graphics API turns off a monitor until I cycle it. The only time I'm having this now is occasionally a few programs that use OpenGL graphics. (Monitors turning off/back on was happening a lot with the Acer-provided DisplayPort cables, but replacing them with certified Accell UltraAV DisplayPort cables fixed that.) When I turn it back on, KDE/Plasma properly re-adds it, gives it the right resolution, rotation, and alignment next to the other monitors.
