I'm using a Radeon RS780. Reverting commit 379dfc25e257ffe10eb53b86d2375f7c0f4f33ef Author: Alex Deucher Date: Mon Apr 7 10:33:46 2014 -0400 drm/radeon/dp: switch to the common i2c over aux code Provides a nice cleanup in radeon. Signed-off-by: Alex Deucher Signed-off-by: Christian König Restores the display - no more i2c errors I have dmesgs of all three tests if anyone wants them.

I managed to get dmesg(s) from 14.1 and 15-rc2. The major difference has to do with i2c.
