Bug ID: 97025 Summary: flip queue failed: Device or resource busy Product: DRI Version: unspecified Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: linux@bernd-steinhauser.de
Since last week I have random freezes with the amdgpu driver (running on Kaveri).
Once the issue occurs the display freezes. It's not fixable by switch to VT2 and back.
In Xorg.0.log I can find multiple times: [ 92357.021] (WW) AMDGPU(0): flip queue failed: Device or resource busy [ 92357.021] (WW) AMDGPU(0): Page flip failed: Device or resource busy [ 92357.021] (EE) AMDGPU(0): present flip failed
No related messages in the journal or dmesg afaics.
It does not seem to be related to a specific event (like a video playing), but just happens out of nowhere. I didn't find a way to reproduce it specifically.
Possibly related packages that I built in that time: * dev-lang/llvm-scm::arbor 2016-06-11 07:42:19 UTC * dev-lang/llvm-scm::arbor 2016-06-19 07:29:42 UTC * x11-dri/mesa-12.0.0-rc4::x11 2016-06-21 21:40:48 UTC * dev-lang/llvm-scm::arbor 2016-07-02 11:57:34 UTC * dev-lang/clang-scm::arbor 2016-07-02 12:43:00 UTC * dev-lang/llvm-3.8.0-r1::arbor 2016-07-12 20:04:14 UTC * dev-lang/clang-3.8.0::arbor 2016-07-12 20:48:27 UTC * x11-dri/mesa-12.0.0::x11 2016-07-13 04:42:47 UTC * x11-dri/mesa-12.0.1::x11 2016-07-17 14:25:44 UTC * x11-server/xorg-server-1.18.4::x11 2016-07-20 16:06:18 UTC
I couldn't get mesa 12 to built with llvm-scm anymore, so I downgraded. Still, I doubt it's related.
It's hard to be certain about this, but it could have been a regressing coming with mesa 12 and possibly mesa-12.0.0. I'm pretty sure I haven't seen the freeze before 12.0.0 final, but it's hard to be certain about this with an issue so random.
In case it matters, my xorg settings are: Section "Device" Identifier "AMDGPU" Driver "amdgpu" Option "TearFree" "Off" Option "EnablePageFlip" "On" Option "DRI" "3" EndSection
IIRC, this is now standard, so nothing special here.
