<pre>I'm running latest Debian Stretch on a ThinkPad X1 Carbon 20A7 "Linux mkjlap
4.5.0-2-amd64 #1 SMP Debian 4.5.3-2 (2016-05-08) x86_64 GNU/Linux"
I often get the following dmesg error when unplugging a DP cable or undocking
from the dock:
i915 0000:00:02.0: BAR 6: [??? 0x00000000 flags 0x2] has bogus alignment
Sometimes its accompanied with a:
[drm:intel_mst_disable_dp [i915]] *ERROR* failed to update payload -22
The system seems to work properly mostly, but sometimes, when using a cable, my
monitor doesn't seem to detect any visual and goes to standby, but xrandr
claims that the monitor is enabled. To fix this I "--off" the monitor manually
and "--auto" the monitor right after.</pre>
