agd5f 4.17-wip with only with amdgpu.dc=1 I can hang display with Unreal tournament demo, backtrace at end of attached dmesg. The game notices and times out after 30sec and I regain display. This is just on initial menu possibly moving mouse to trigger - time taken to trigger 1 - 5 seconds.

Other things seem OK, but there is also rare display glitch in normal use where it seems that a black frame is displayed or something. May be luck, and I've only seen it a few times, but was moving mouse at the time.

No bisect, recent bugs seem to go away next update anyway + the last "DC team" bug I took time to bisect has been unanswered since December - though it may be very specific to my setup, unanswered = less motivation to bisect.
