Radeon monitor + hdmi TV regression between drm-core-next and drm-fixes

For the last 2 years when running a DVI 60Hz monitor with a radeon HD4890 and a (native 50Hz) HDMI TV I've been able to boot/startx with the TV off and then turn TV on and -

xrandr --output DVI-0 --auto

to bring up the the TV and get a clone of monitor.

This still works with drm-core-next but not with drm-fixes (todays or from a few days ago).

With df I now loose the monitor with signal out of range when doing above, the TV output is OK. To get the monitor back I need to turn off TV, then off/auto the monitor.

xrandr --output DVI-0 --off xrandr --output DVI-1 --off xrandr --output DVI-1 --auto

The output from xrandr while the monitor is showing signal out of range looks normal.

If I boot with the TV on it works OK.
