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.

--- Comment #4 from Michel Dänzer michel@daenzer.net --- Does this still happen with current xf86-video-ati Git, or at least the 7.7.1 release?

--- Comment #5 from Vedran Miletić vedran@miletic.net --- Testing. Looks good and haven't had it happen thus far, will report in a few days. Bug 176301 is still occuring.
https://bugzilla.kernel.org/show_bug.cgi?id=176311
--- Comment #6 from Vedran Miletić vedran@miletic.net --- Still happens with xorg-x11-drv-ati-7.7.1-1.20160928git3fc839ff
https://bugzilla.kernel.org/show_bug.cgi?id=176311
--- Comment #7 from Michel Dänzer (michel@daenzer.net) --- Does https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... help for this, by any chance?
BTW, I made a mistake in comment 4, need to test xf86-video-amdgpu here, not xf86-video-ati.
