--- Comment #32 from Chris Wilson <chris at chris-wilson.co.uk> ---
(Oops was thinking of the other multiple monitor regressions in the kernel).
The issue here is that state we read back from the CRTC and create a mode from
does not always correspond with the mode we create from the EDID mode list -
notably the CRTC flags go astray.
