Comment 2 Tom D 2018-02-20 13:36:43 UTC 
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 logging 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). 

Same symptoms on numerous docs. 

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

Here is my dmesg snippet, note the first MMIO fault isn't at the same address.

The read fault at 10ac08 happens only ones during system boot, read fault 6013d4 happens apparently every time I suspend/resume.
