<pre>I've got this error yesterday after plugging a Dell monitor on my T450 through
DisplayPort.
I am not sure if the error happened right after plugging it or a few seconds
later.
The error does not seem to occur every time I light up the display, only
sometimes.
I tried to reproduce it again and I cannot reproduce it. The display otherwise
works normally and I get no freezes/hangs.
I'm on Arch Linux, Linux kernel 4.18.16-arch1-1-ARCH, using modesetting drivers
and i3-wm.</pre>
