Hi,
Recently, after resume from suspend or just switched off-on the TV, the
screen gets sometimes frozen. I'm still able to switch to a vt. Trying
to reconfigure with "xrandr --output HDMI-0 --auto" shows “Configure
CRTC 0 failed”.
The normal xrandr output on my system is:
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 16384 x 16384
HDMI-0 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 886mm

But differs when failed:

Also, looking at "xrandr --verbose" output I can see that the line
CRTC: 0
disappears.
This bug appeared after upgrading my system (Debian testing, custom
Linux kernel 4.0.4):
xserver-xorg 7.7
xserver-xorg-video-radeon 7.5.0
Any idea about what's happening?
Best Regards,
