Hi,

I noticed that one machine here gives only the blank output with
3.4-rc's. The bisection lead me to affecting commit:

commit e00e8b5e760cbbe9067daeae5454d67c44c8d035

drm/radeon/kms: fix analog load detection on DVI-I connectors

Reverting this commit helped, it goes back to normal.

On this system, the VGA monitor is connected to DVI over a VGA-DVI
connector (and even VGA-switcher). So, yeah, it's a strange setup.
But a regression is a regression.

I'm willing to test any patch.


thanks,

Takashi
