Hi guys,
so I'm booting 15-rc1 + tip/master and around the time modesetting gets initialized, the screen blanks and on it appears a message from the monitors:
"The current input timing is not supported by the monitor display. Please change your input timing to 1920x1200@60Hz or any other monitor listed timing as per the monitor specifications."
The box is still responsive, I can reboot it with Ctrl-Alt-Del but screens are blank.
If I boot with radeon.modeset=0, I see the normal nomodeset big letters on the console and not very optimal screen resolution.
Diffing drm init chatter from dmesg shows only this:

Below is the whole thing, btw.
Anyway, if you guys have any ideas, I'm all ears. Otherwise, would a quick bisect on the 59 patches touching drivers/gpu/drm/radeon/ make sense?
git log --oneline v3.14.. drivers/gpu/drm/radeon/ | wc -l 59
Thanks.
