Subject: [Bug 176311] New: Fiji DisplayPort amdgpu_crtc_page_flip *ERROR* failed to get vblank before flip
Date: Tue, 04 Oct 2016 19:42:47 +0000	[thread overview]
Message-ID: <bug-176311-2300@https.bugzilla.kernel.org/> (raw)

https://bugzilla.kernel.org/show_bug.cgi?id=176311

            Bug ID: 176311
           Summary: Fiji DisplayPort amdgpu_crtc_page_flip *ERROR* failed
                    to get vblank before flip
           Product: Drivers
           Version: 2.5
    Kernel Version: 4.7.5-200.fc24.x86_64
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org
          Reporter: vedran@miletic.net
        Regression: No

As said in bug 176301, I have a Fiji card

01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Fiji
[Radeon R9 FURY / NANO Series] (rev ca)

with two LG DisplayPort 27" 4K monitors. Locking screen while GNOME is running
on X makes both monitors go to sleep, all fine. Upon moving a mouse or pressing
a key, only one of them will wake up, and always the same one. Dmesg shows:

[drm:amdgpu_crtc_page_flip [amdgpu]] *ERROR* failed to get vblank before flip

The other monitor will wake up if one switches to a console (e.g. Ctrl+Alt+F3)
and back or one powers any of the monitors off and back on.
