I have already commented on bogus modes when the patch first went into 
dcn, but to repeat -

HDMI TV - lots of new modes but it already advertised all the CVT that 
it supports and all the new are bogus.

DVI 120Hz 1920x1080 monitor many bogus modes as it won't display > it's 
res and won't scale up some of the new modes.

Even some of the new ones that are not "out of range" will actually end 
up setting something different and show some distortion.

Maybe gained a couple.
