Bugzilla Automation <bugzilla@FreeBSD.org> has asked freebsd-x11 (Nobody) <x11@FreeBSD.org> for maintainer-feedback: Bug 248777: graphics/drm-devel-kmod: Panic when transcoding a video https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D248777 --- Description --- Hi, I'm running 13.0-CURRENT r364031 with latest drm-devel-kmod installed as I needed support for the graphics chipset of my Celeron G5900. The kernel reliably panics when transcoding a certain video with Plex which leverages libva (hence the graphics chipset). I have an ongoing discussion about it : https://lists.freebsd.org/pipermail/freebsd-current/2020-August/076728.html The interesting part is that the panic never happen when I plug a screen on HDMI port and happens all the time when no screen plugged. The frame #17 fr= om the backtrace refers to intel_plane_can_remap() so there might be hint in there. I dumped the content of structures from several backtrace frames that you c= an see in the discussion linked above. Thanks.
