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.=
