Commen= t # 2 on bug 10483= 5 from Tom D 
Hardware: Lenovo P50
Symptoms:
This problem did not happen until I dist-upgraded from Fedora 26 to 27.

If the laptop is connected to the dock during boot, I get the logs below and
nothing further. I cannot shift desktops, log in, etc. Due to the
configuration, I cannot remotely SSH in without changing the FW after loggi=
ng
in so I'm unsure about that behavior.

If I boot the system off of the doc and then place it into the doc before
logging in as a user, all seems to work well. I can then remove and re-seat=
 the
laptop without issue.

If I boot the system, log in and then place it on the doc, sometimes (I do =
not
understand the pattern), the second screen attached to the dock is not seen=
 at
all (does not show under displays).=20

Same symptoms on numerous docs.=20

I am concerned that the nouveau errors seen are unrelated to the actual
problems encountered.
