--- Comment #1 from Martin (martin.tk@gmx.com) --- I think I may be experiencing a similar problem.
I had 2 random system freezes, the kind when nothing can be done (the second time I had the characteristic audio freeze).
Both freezes happened when I was stopping audio playback and/or the screen was in the stand by mode. ( I was switching screen's input to Display Port which is the PC that froze). The screen is Dell U2515H (it doesn't have speakers, I use audio out mini-jack on the motherboard for audio output).
I haven't experiences such issues on the previous kernel version.
I don't have amdgpu.dc=1 on kernel cmdline but as I understand it it's the new default for 4.17.0
I started getting this kind of traces in my logs:
