I am experiencing an issue where my system hangs instead of properly shutting
down when my laptop is docked. One of my monitors has EDID issues, so I have
to force an EDID using drm.edid. I noticed that when I remove the parameter, I
have no issues shutting down. This issue occurs on the current drm-tip kernel
(compiled as of commit e2561817d912857cdf7437e73a8fb41256d06edb.) I believe
this may be a regression as I do not remember it happening before, but I will
need to do more digging to find a previous kernel version that works.
Thinkpad X270 i7-7500U
UEFI version: R0IET58W (1.36)
How often: always
Steps to reproduce:
-Boot up laptop and login
-Close lid and put it on the dock
-Shutdown with the laptop still on the dock</pre>
