You have six kernel boots in your logs, five of which are not even with a MST
configuration. Can you please attach only logs that are relevant? More
importantly, the errors you are seeing are not related to this bug, you should
create a new bug and document the reproduction steps, not just the
configuration.
Even the configuration has contradicting statements
"displays connected : DP-2 DP-4 DP-8" and "Two external monitors with
DP/mDP cable connected to MST."
The final log shows you have three displays connected, please document your MST
configuration correctly.</pre>
