Bug ID: 105414
Summary: R9 285 agd5f 4.17-wip DC flip_done timed out
Product: DRI
Version: DRI git
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: DRM/AMDgpu
Assignee: dri-devel@lists.freedesktop.org
Reporter: adf.li...@gmail.com

dmesg with errors and bt
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.
