Yeah, interestingly I had one similar event last evening. Upon starting the X user session from lightdm the eDP link failed and was unable to sync again. Also there seems to be a correlation between enabling i2s0 and i2s2 and failure of the eDP link. Thus I disabled i2s0 and i2s2 in my devicetree. It is happening too seldomly to me to pin it to anything yet though.
EDIT: I've pushed an additional commit to my gitlab branch that slows the display clock a tat. While I don't think it will make any difference you are welcome to test it out.
