--- Comment #16 from Nicholas Stommel <nicholas.stommel at gmail.com> ---
Interestingly, this behavior does not always happen, suggesting that it may be
a timing issue indeed. The seemingly random nature of it is confounding. Using
the kernel parameter "drm.debug=0x1e", this behavior cannot be replicated for
some reason. Booting without that parameter, the issue is very reliably
reproduced, much closer to (if not over) half of all boots on 4.16-rc1 all the
way to drm-tip.
