--- Comment #4 from Kevin wittyman37@yahoo.com --- I did not change any hardware. I tried changing the connection to the monitor because I had issues a few months back with DisplayPort but that didn't help here. I don't seem to have an xorg log in /var/log/ but and the most interesting line of my dmesg was what I included above...
[drm:si_dpm_set_power_state [radeon]] *ERROR* si_restrict_performance_levels_before_switch failed
I built the 4.2rc8 from git last night and the issue is still there. I am going to get the entire dmesg for you now.
