Created attachment 134319 [details] Crash dump from /sys/class/drm/card0/error as requested in dmesg. Black screen when trying to play Video in Mythfrontend. Happens only occasionally, perhaps 1 in 20 tries. Intel NUC7i3BNH 4.12.0-13-generic HDMI connection Driver installed from Ubuntu 17.10 repos.
It doesn't look consistent with kbl lite-restore failure, more of a typical hang on a pipe-control following the batch. First step is then to validate the GL batch.
I'm more than happy to provide anything needed to resolve this, but I'm not a developer so please be specific about what you need from me, thanks.
Hello Erik, Could you please share your mesa version, distro, desktop and if possible could you try latest kernel stable and mesa 17.3 or up? Thank you. https://www.kernel.org https://www.mesa3d.org
Mesa: 17.2.2 Distro: XUbuntu 17.10 Desktop: XFCE 4.12 Sorry, I don't really have the know-how to test latest kernel. Thanks
This may help, the preparing, mesa and kernel sections: https://01.org/linuxgraphics/documentation/build-guide-0
