It looks like a GPU hang.  I think the displayport failure is just a side
effect of that.  Does it work if you disable acceleration in X?  To disable
acceleration, add an /etc/X11/xorg.conf file with the following content:

Section "Device"
        Identifier              "Device0"
        Driver                  "radeon"
        Option                  "NoAccel" "true"
