Created attachment 276323 --> https://bugzilla.kernel.org/attachment.cgi?id=276323&action=edit dmesg error when connecting tv via hdmi
Booting 4.17 kernel (with amdgpu.dc=1 )with HDMI-TV connected results in system-freeze (unable to ssh / change tty, etc)
If I connect the tv after logging into a graphical session (gnome 3.28) i get a video-signal.
When I select HDMI-Audio output with pavucontrol (since it's not even listed in Gnome) my system will still freeze.
Trying to play some audiofile with aplay -D on that device will also freeze my system (sometimes even just aplay -l will cause a freeze)
I have attatched the dmesg-output after connecting the tv with hdmi
my system:
Kernel: 4.17.0 DE: GNOME 3.28.2 CPU: Intel Core i5-4690S GPU: AMD Radeon R9 290
