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) expec=
ted
"[drm]" lines about the "new" connection.

See attached file for a sample of the kernel warnings/stack traces.  The fi=
rst
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 somewher=
e 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.
