Created attachment 94554 --> https://bugs.freedesktop.org/attachment.cgi?id=94554&action=edit dmesg radeon 6850
I'm running Fedora 20 with the latest distro kernel (3.13.3). I'm running Gnome shell and see very frequent hangs. Its usually observed when the system has been inactive for a while and the monitor goes into powersave mode. When I try to activate the system via keyboard/mouse I get a black screen. I cannot switch to a VT as well. SSH still works and the system is responsive via ssh. DPM is not enabled. However I did switch the card to "low" power profile after boot.
echo "low" > /sys/class/drm/card0/device/power_profile
