Not sure if this is bug, the aux transaction failed on the external DP port when doing the probing to setup the test environment probably due to some issue on the monitor as 100ms later the monitor triggered a long pulse and then i915 was able to probe the monitor.

So a real user it would have no impact, for CI it could have caused the test to fail if the external monitors was being used on the test. It is very likely this a issue on the monitor that auto recovered itself and send the long pulse.

How to do you see this issue? Is it having the same impact as above?

The same thing as described in comment 2 happened but this time it took more 10sec to i915/display to recover it self.
