https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D248777 Bug ID: 248777 Summary: graphics/drm-devel-kmod: Panic when transcoding a video Product: Ports & Packages Version: Latest Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: Individual Port(s) Assignee: x11@FreeBSD.org Reporter: a13xlevy@gmail.com Assignee: x11@FreeBSD.org Flags: maintainer-feedback?(x11@FreeBSD.org) Created attachment 217372 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D217372&action= =3Dedit Backtrace of the generated crash dump 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. --=20 You are receiving this mail because: You are the assignee for the bug.=
