I found another kernel panic situation when playing DVD's, kinda similar to the one I detailed in #214705. This one is more subtle, however= , as it appears to be triggered by something in the amd64 trampoline code when attempting to restart DVD playback after resuming from a suspend that was d= one while the DVD was playing. The issue is triggered on a custom kernel that is basically just GENERIC with some unneeded devices/options removed to cut the kernel image's size down. I'll attach my config to this bug.

() Current language: auto; currently minimal (kgdb)=20 Steps to reproduce: 1. Insert DVD. 2. Unmount auto-mounted instance from /media. 3. Launch VLC and "Play Disc". 4. Start playing the disc. 5. Puse playback and close the lid on the laptop to put it into suspend. 6. Wait a few seconds until it is fully in suspend, then open the laptop li= d. 7. Wait for the auto-mounter to re-mount the DVD (icon appears on the deskt= op). 8. Restart playback in VLC while the DVD is auto-mounted to /media. 9. Bada-boom! I have not tried this on a GENERIC kernel yet, as part of the reproduction steps requires playing the DVD while it is auto-mounted to /media, and this might trip up the bug described in #214705, as I haven't seen an updated GENERIC kernel come down the pipe yet that contains the fix for that. My custom kernel patches that issue locally for now. The hardware in question is an HP 2000-2b19wm notebook. I can provide additional information if needed to troubleshoot this issue. dmesg: # dmesg Copyright (c) 1992-2016 The FreeBSD Project.
