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 at 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: --- /tmp/working 2014-04-15 08:40:21.979985352 +0200 +++ /tmp/b0rked 2014-04-15 08:40:11.983985364 +0200 @@ -44,4 +44,5 @@ [drm] pitch is 7680 fbcon: radeondrmfb (fb0) is primary device radeon 0000:01:00.0: fb0: radeondrmfb frame buffer device -[drm] Initialized radeon 2.37.0 20080528 for 0000:01:00.0 on minor 0 +[drm] Initialized radeon 2.38.0 20080528 for 0000:01:00.0 on minor 0 + 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.
