3.3.8 is the baseline, on which the display port monitor works fine. 3.4.2.cold is a cold boot into 3.4.2. The monitor on the display port remains blank. That is, it displays "No Signal Input" and then enters power saving mode. 3.4.2 is a reboot after running 3.3.8 first. Now the monitor attached to the display port works too. The main difference between 3.4.2 and 3.4.2.cold seems to be that a warm boot reports "clock recovery OK", whereas a cold boot fails trying to train the link. I did have a look at the (many) differences between 3.3.8 and 3.4.2, but I can't see anything that looks important. I will happily leave further interpretation to you. I hope this will give someone an idea. In the mean while I will redo the bisect.
