--- Comment #6 from Joseph Yasi <joe.yasi at gmail.com> ---
I just tried 4.12-rc7 at git b4df2e35. The frequency of modeset failures as
increased to about 50% of the time. Sometimes the modeset fails on boot and I
get a black screen. I have to ssh in to toggle modes until one sticks. I've had
it fail setting the console mode before X starts.

Any ideas on why these modesets are failing? This is a very frustrating bug
that severely impacts usability.
