Radeon 77xx xorg issue on cyrus+ Varisys

This are my logs of experience on a 7750HD 2GB
I attached my dmesg radeon,drm and Xorg logs for gave better investigating to the devs.
I see on Xorg.1.log where the radeon config was called there is a crash on radeonsi 

a drm:.si_dpm_set_power_state] *ERROR*  too.


Hope it will help for have a great linux experiences on this new powerpc desktop machine

Thanks for support ppc
