Dunno, but it's a quite interesting clue.
Thanks for copying your info upstream, hopefully it'll give them some specific ideas.

Glad to hear that toggling the LVDS1 serves as a workaround. It also suggests there may be a race condition going on here or something. I'm curious what ratio of times it works, roughly? Like 10%? 50%? 75%?
